[PATCH net-next v6 00/12] net: pcs: Introduce support for fwnode PCS

[PATCH net-next v6 00/12] net: pcs: Introduce support for fwnode PCS

[Christian Marangi]

This series introduce a most awaited feature that is correctly
provide PCS with fwnode without having to use specific export symbol
and additional handling of PCS in phylink.

At times there were 2 different implementation (this and the one
from Sean) but Sean agreed that this can be picked and used in favor
of his implementation as long as his case with race condition is
correctly handled.

---
First the PCS fwnode:

The concept is to implement a producer-consumer API similar to other
subsystem like clock or PHY.

That seems to be the best solution to the problem as PCS driver needs
to be detached from phylink and implement a simple way to provide a
PCS while maintaining support for probe defer or driver removal.

To keep the implementation simple, the PCS driver devs needs some
collaboration to correctly implement this. This is O.K. as helper
to correctly implement this are provided hence it's really a matter
of following a pattern to correct follow removal of a PCS driver.

A PCS provider have to implement and call fwnode_pcs_add_provider() in
probe function and define an xlate function to define how the PCS
should be provided based on the requested interface and phandle spec
defined in fwnode (based on the #pcs-cells)

fwnode_pcs_get() is provided to provide a specific PCS declared in
fwnode at index.

A simple xlate function is provided for simple single PCS
implementation, fwnode_pcs_simple_get.

A PCS provider on driver removal should first call
fwnode_pcs_del_provider() to delete itself as a provider and then
release the PCS from phylink with phylink_release_pcs() under rtnl
lock.

---
Second PCS handling in phylink:

We have the PCS problem for the only reason that in initial
implementation, we permitted way too much flexibility to MAC driver
and things started to deviate. At times we couldn't think SoC
would start to put PCS outside the MAC hence it was OK to assume
they would live in the same driver. With the introduction of
10g in more consumer devices, we are observing a rapid growth
of this pattern with multiple PCS external to MAC.

To put a stop on this, the only solution is to give back to phylink
control on PCS handling and enforce more robust supported interface
definition from both MAC and PCS side.

It's suggested to read patch 0003 of this series for more info, here
a brief explaination of the idea:

This series introduce handling of PCS in phylink and try to deprecate
.mac_select_pcs.

Phylink now might contain a linked list of available PCS and
those will be used for PCS selection on phylink_major_config.

MAC driver needs to define pcs_interfaces mask in phylink_config
for every interface that needs a dedicated PCS.

These PCS needs to be provided to phylink at phylink_create time
by setting the available_pcs and num_available_pcs in phylink_config.
A helper to parse PCS from fwnode is provided
fwnode_phylink_pcs_parse() that will fill a preallocated array of
PCS. (the same function can be used to get the number of PCS
defined in DT, more info in patch 0005)

phylink_create() will fill the internal PCS list with the passed
array of PCS. phylink_major_config and other user of .mac_select_pcs
are adapted to make use of this new PCS list.

The supported interface value is also moved internally to phylink
struct. This is to handle late removal and addition of PCS.
(the bonus effect to this is giving phylink a clear idea of what
is actually supported by the MAC and his constraint with PCS)

The supported interface mask in phylink is done by OR the
supported_interfaces in phylink_config with every PCS in PCS list.

PCS removal is supported by forcing a mac_config, refresh the
supported interfaces and run a phy_resolve().

PCS late addition is supported by introducing a global notifier
for PCS provider. If a phylink have the pcs_interfaces mask not
zero, it's registered to this notifier.

PCS provider will emit a global PCS add event to signal any
interface that a new PCS might be avialable.

The function will then check if the PCS is related to the MAC
fwnode and add it accordingly.

A user for this new implementation is provided as an Airoha PCS
driver. This was also tested downstream with the IPQ95xx QCOM SoC
and with the help of Daniel also on the various Mediatek MT7988
SoC with both SFP cage implementation and DSA attached.

Lots of tests were done with driver unbind/bind and with interface
up/down also by adding print to make sure major_config_fail gets
correctly triggered and reset once the PCS comes back.

The dedicated commits have longer description on the implementation
so it's suggested to also check there for additional info.

It's worth to mention that OpenWrt is currently using this on
Mediatek SoC and QCOM ipq807x/ipq60xx/ipq50xx and Airoha are
already ported in staging tree for testing.

[PATCH net-next v6 01/12] net: phylink: keep and use MAC supported_interfaces in phylink struct

[Christian Marangi]

Add in phylink struct a copy of supported_interfaces from phylink_config
and make use of that instead of relying on phylink_config value.

This in preparation for support of PCS handling internally to phylink
where a PCS can be removed or added after the phylink is created and we
need both a reference of the supported_interfaces value from
phylink_config and an internal value that can be updated with the new
PCS info.

[PATCH net-next v6 02/12] net: phylink: introduce internal phylink PCS handling

[Christian Marangi]

Introduce internal handling of PCS for phylink. This is an alternative
way to .mac_select_pcs that moves the selection logic of the PCS entirely
to phylink with the usage of the supported_interface value in the PCS
struct.

MAC should now provide a callback to fill the available PCS in
phylink_config in .fill_available_pcs and fill the .num_available_pcs with
the number of elements in the array. MAC should also define a new bitmap,
pcs_interfaces, in phylink_config to define for what interface mode a
dedicated PCS is required.

On phylink_create(), an array of PCS pointer is allocated of size
.num_available_pcs from phylink_config and .fill_available_pcs from
phylink_config is called passing as args the just allocated array and
the number of available element in it.

MAC will fill this passed array with all the available PCS.

This array is then parsed and a linked list of PCS is created based on
the allocated PCS array filled by MAC via .fill_available_pcs().
Also the supported_interface value in phylink struct is updated with the
new supported_interface from the provided PCS.

On phylink_start() every PCS in phylink PCS list gets attached to the
phylink instance. This is done by setting the phylink value in
phylink_pcs struct to the phylink instance.

On phylink_stop(), every PCS in phylink PCS list is detached from the
phylink instance. This is done by setting the phylink value in
phylink_pcs struct to NULL.

phylink_validate_mac_and_pcs(), phylink_major_config() and
phylink_inband_caps() are updated to support this new implementation
with the PCS list stored in phylink.

They will make use of phylink_validate_pcs_interface() that will loop
for every PCS in the phylink PCS available list and find one that supports
the passed interface.

phylink_validate_pcs_interface() applies the same logic of .mac_select_pcs
where if a supported_interface value is not set for the PCS struct, then
it's assumed every interface is supported.

A MAC is required to implement either a .mac_select_pcs or make use of
the PCS list implementation. Implementing both will result in a fail
on MAC/PCS validation.

A MAC defining .num_available_pcs in phylink_config MUST also define a
.fill_available_pcs or phylink_create() will fail with an negative error.

phylink value in phylink_pcs struct with this implementation is used to
track from PCS side when it's attached to a phylink instance. PCS driver
will make use of this information to correctly detach from a phylink
instance if needed.

The .mac_select_pcs implementation is not changed but it's expected that
every MAC driver migrates to the new implementation to later deprecate
and remove .mac_select_pcs.

[PATCH net-next v6 03/12] net: phylink: add phylink_release_pcs() to externally release a PCS

[Christian Marangi]

Add phylink_release_pcs() to externally release a PCS from a phylink
instance. This can be used to handle case when a single PCS needs to be
removed and the phylink instance needs to be refreshed.

On calling phylink_release_pcs(), the PCS will be removed from the
phylink internal PCS list and the phylink supported_interfaces value is
reparsed with the remaining PCS interfaces.

Also a phylink resolve is triggered to handle the PCS removal.

The flag force_major_config is set to make phylink resolve reconfigure
the interface (even if it didn't change) is also added.
This is needed to handle the special case when the current PCS used
by phylink is removed and a major_config is needed to propagae the
configuration change. With this option enabled we also force mac_config
even if the PHY link is not up for the in-band case.

[PATCH net-next v6 04/12] net: pcs: implement Firmware node support for PCS driver

[Christian Marangi]

Implement the foundation of Firmware node support for PCS driver.

To support this, implement a simple Provider API where a PCS driver can
expose multiple PCS with an xlate .get function.

PCS driver will have to call fwnode_pcs_add_provider() and pass the
firmware node pointer and a xlate function to return the correct PCS for
the passed #pcs-cells.

This will register the PCS in a global list of providers so that
consumer can access it.

The consumer will then use fwnode_pcs_get() to get the actual PCS by
passing the firmware node pointer and the index for #pcs-cells.

For a simple implementation where #pcs-cells is 0 and the PCS driver
expose a single PCS, the xlate function fwnode_pcs_simple_get() is
provided.

For an advanced implementation a custom xlate function is required.

One removal the PCS driver should first delete itself from the provider
list using fwnode_pcs_del_provider() and then call phylink_release_pcs()
on every PCS the driver provides.

A generic function fwnode_phylink_pcs_parse() is provided for MAC driver
that will declare PCS in DT (or ACPI).
This function will parse "pcs-handle" property and fill the passed array
with the parsed PCS in available_pcs up to the passed num_pcs value.
It's also possible to pass NULL as array to only parse the PCS and
update the num_pcs value with the count of scanned PCS.

[PATCH net-next v6 05/12] net: phylink: support late PCS provider attach

[Christian Marangi]

Add support for late PCS provider attachment to a phylink instance.
This works by creating a global notifier for the PCS provider and
making each phylink instance that makes use of fwnode subscribe to
this notifier.

The PCS notifier will emit the event FWNODE_PCS_PROVIDER_ADD every time
a new PCS provider is added.

phylink will then react to this event and will call the new function
fwnode_phylink_pcs_get_from_fwnode() that will check if the PCS fwnode
provided by the event is present in the pcs-handle property of the
phylink instance.

If a related PCS is found, then such PCS is added to the phylink
instance PCS list.

Then we link the PCS to the phylink instance if it's not disabled and we
refresh the supported interfaces of the phylink instance.

Finally we check if we are in a major_config_failed scenario and trigger
an interface reconfiguration in the next phylink resolve.

In the example scenario where the link was previously torn down due to
removal of PCS, the link will be established again as the PCS came back
and is now available to phylink.

+PCS Subsystem
+=============
+
+The PCS (Physical Coding Sublayer) subsystem handles the registration and lookup
+of PCS devices. These devices contain the upper sublayers of the Ethernet
+physical layer, generally handling framing, scrambling, and encoding tasks. PCS
+devices may also include PMA (Physical Medium Attachment) components. PCS
+devices transfer data between the Link-layer MAC device, and the rest of the
+physical layer, typically via a serdes. The output of the serdes may be
+connected more-or-less directly to the medium when using fiber-optic or
+backplane connections (1000BASE-SX, 1000BASE-KX, etc). It may also communicate
+with a separate PHY (such as over SGMII) which handles the connection to the
+medium (such as 1000BASE-T).
+
+Remark on usage of .mac_select_pcs and fw_node PCS
+--------------------------------------------------
+
+There are generally two ways to look up a PCS device.
+
+1. MAC OP struct .mac_select_pcs (considered legacy)
+2. firmware node (fwnode) PCS entirely handled by phylink
+
+Implementation 1 leaves the entire handling of the PCS to the MAC
+driver with the selection of the PCS driven by .mac_select_pcs.
+Custom implementations are required if the PCS is external to the MAC
+and needs to be handled by a separate driver.
+
+This implementation is considered legacy and it's suggested to
+switch to the new fwnode PCS.
+
+Looking up PCS Devices (fwnode implementation)
+-----------------------------------------------
+
+The lookup of a PCS device follows the common producer/consumer implementation
+used by similar subsystem with a ``#pcs-cells`` on the producer and a
+``pcs-handle`` property on the consumer::
+
+    pcs: pcs {
+        // ...
+        #pcs-cells = <0>;
+    };
+
+    ethernet-controller {
+        // ...
+        pcs-handle = <&pcs>;
+    };
+
+On :c:func:`phylink_create`, phylink will use the ``num_available_pcs``
+value and ``fill_available_pcs`` helper function in
+:c:struct:`phylink_config` to compose the list of available PCS that can be
+used for the phylink instance.
+
+Phylink will then internally handle the selection of the correct PCS for
+the requested interface mode based on the interface modes configured in
+``pcs_interfaces`` in :c:struct:`phylink_config` struct and
+``supported_interfaces`` in :c:struct:`phylink_pcs` struct.
+
+A PCS is considered eligible when the requested interface mode is present
+in both ``pcs_interfaces`` in :c:struct:`phylink_config` struct and
+``supported_interfaces`` in :c:struct:`phylink_pcs` struct.
+
+``supported_interfaces`` describes all interface modes supported by the MAC,
+whereas ``pcs_interfaces`` identifies the subset that require PCS selection.
+
+For the special implementation where the PCS is internal or part of the MAC
+and a dedicated driver is not needed, it's possible to leave the implementation
+of the PCS to the MAC driver and just implement the ``num_available_pcs``
+value and ``fill_available_pcs`` helper  function in
+:c:struct:`phylink_config` referencing the local :c:struct:`phylink_pcs`
+struct allocated from the MAC driver.
+
+Using PCS Devices
+-----------------
+
+It's mandatory to either implement the ``mac_select_pcs`` callback
+of :c:struct:`phylink_mac_ops` or ``num_available_pcs`` and ``fill_available_pcs`` of :c:struct:`phylink_config` to use a PCS
+for a MAC.
+
+The fwnode implementation expose a simple helper to parse the PCS from
+the fwnode :c:func:`fwnode_phylink_pcs_parse`. The helper takes three arguments,
+the fwnode where the ``pcs-handle`` should be parsed, an allocated array
+of :c:struct:`phylink_pcs` pointer where to put the parsed PCS from the fwnode
+and a pointer to the maximum number of PCS to parse. The helper can also be used
+to obtain the number of PCS parsed (without filling the array) by passing
+``NULL`` for the second arg. In such case, the third arg will be set to the
+number of PCS parsed in the fwnode.
+
+A phylink instance may use multiple PCS devices. The maximum number is reported
+through ``num_available_pcs``.
+
+It's mandatory to specify for what interface a PCS is needed. This can be done
+by filling the ``pcs_interfaces`` in :c:struct:`phylink_config` struct.
+If the requested interface mode is not present in this bitmask, phylink does
+not search for a PCS for  that specific mode. (example MAC doesn't need a PCS
+for SGMII but require one for USXGMII)
+
+With the use of the :c:func:`fwnode_phylink_pcs_parse` a common implementation
+is the following::
+
+   static int mac_fill_available_pcs(struct phylink_config *config,
+   				                      struct phylink_pcs **available_pcs,
+   				                      unsigned int num_available_pcs)
+   {
+   	struct device *dev = config->dev;
+
+   	return fwnode_phylink_pcs_parse(dev_fwnode(dev), available_pcs,
+   					                    &num_available_pcs);
+   }
+
+   static int mac_setup_phylink(struct net_device *netdev)
+   {
+      struct phylink_config *config;
+
+      // ...
+
+      config->dev = &netdev->dev;
+
+      // ...
+
+      // Parse available PCS and fill num_available_pcs.
+      err = fwnode_phylink_pcs_parse(dev_fwnode(&netdev->dev), NULL,
+                                     &config->num_available_pcs);
+      if (err)
+         return err;
+
+      config->fill_available_pcs = mac_fill_available_pcs;
+
+      __set_bit(PHY_INTERFACE_MODE_INTERNAL, config->supported_interfaces);
+      __set_bit(PHY_INTERFACE_MODE_SGMII, config->supported_interfaces);
+      __set_bit(PHY_INTERFACE_MODE_1000BASEX, config->supported_interfaces);
+      __set_bit(PHY_INTERFACE_MODE_USXGMII, config->supported_interfaces);
+
+      // PCS required only for USXGMII
+      __set_bit(PHY_INTERFACE_MODE_USXGMII, config->pcs_interfaces);
+
+      phylink = phylink_create(config, //...
+
+It's worth to mention that it's phylink code that takes care of allocating
+the array of :c:struct:`phylink_pcs` pointer for ``fill_available_pcs``
+callback based on the value set in ``num_available_pcs`` for
+:c:struct:`phylink_config` struct.
+
+The ``fill_available_pcs`` callback must not write more than
+``num_available_pcs`` entries. The third argument may be used to validate
+that there is enough space to fill all the available PCS in the passed array
+of :c:struct:`phylink_pcs` pointer.
+
+The ``fill_available_pcs`` callback is called only on :c:func:`phylink_create`
+and is used only to compose the initial available PCS list. Ownership of PCS
+is held by phylink and :c:func:`phylink_release_pcs` should be used to relase
+them.
+
+Writing PCS Drivers
+-------------------
+
+To write a PCS driver, first implement :c:struct:`phylink_pcs_ops`. Then,
+register your PCS in your probe function using :c:func:`fwnode_pcs_add_provider`.
+The :c:func:`fwnode_pcs_add_provider` takes three arg, the fwnode where the PCS
+provider should be registered to, a get function to return the requested PCS
+based on ``#pcs-cells`` and a pointer to reference private data for the get
+function.
+
+The PCS will then be registered to a global list of PCS provider that the
+PCS fwnode implementation will use to parse it.
+
+For the simple case where the PCS driver expose a single PCS,
+:c:func:`fwnode_pcs_simple_get` can be used as the get function.
+
+You must call :c:func:`fwnode_pcs_del_provider` from your remove function and
+release the PCS from any phylink instance under RTNL lock with
+:c:func:`phylink_release_pcs`::
+
+   fwnode_pcs_del_provider(dev_fwnode(&pdev->dev));
+
+	rtnl_lock();
+
+	for (i = 0; i < data->num_port; i++) {
+		struct pcs_port *port = &priv->ports[i];
+
+		phylink_release_pcs(&port->pcs);
+	}
+
+	rtnl_unlock();
+
+Late PCS registration handling
+------------------------------
+
+It's possible that a PCS becomes available after the MAC finished probing.
+Contrary to the usual producer/consumer implementation, when a PCS is not
+registered and can't be found, the fwnode parser helper returns ``-EINVAL``
+instead of ``-EPROBE_DEFER``.
+
+This is to prevent race condition with particular devices that register
+MAC and PCS with USB or PCIe and require the MAC to be registered before
+the PCS.
+
+The phylink logic correctly handle this special case and keep the phylink
+instance in a fail condition.
+
+The PCS fwnode implementation provides a notifier to which each phylink
+instance with a non-empty ``pcs_interfaces`` in :c:type:`phylink_config`
+registers. When a new PCS provider is registered, the notifier is called
+triggering the :c:func:`pcs_provider_notify` function.
+
+Function :c:func:`pcs_provider_notify` will check if the just added PCS
+should be used by the phylink instance. If it should be used then,
+it's added to the internal list of available PCS and a phylink major
+config is forced.
+
+If a phylink instance was in a failure state, with the just added PCS
+now part of the available PCS internal phylink list, provided all other
+conditions are satisfied, the configuration is retried and the failure
+condition is cleared.

[PATCH net-next v6 09/12] net: phylink: add .pcs_link_down PCS OP

[Christian Marangi]

Permit for PCS driver to define specific operation to torn down the link
between the MAC and the PCS.

This might be needed for some PCS that reset counter or require special
reset to correctly work if the link needs to be restored later.

On phylink_link_down() call, the additional phylink_pcs_link_down() will
be called before .mac_link_down to torn down the link.

PCS driver will need to define .pcs_link_down to make use of this.

[PATCH net-next v6 10/12] dt-bindings: net: pcs: Document support for Airoha Ethernet PCS

[Christian Marangi]

Document support for Airoha Ethernet PCS for AN7581 SoC.

Airoha AN7581 SoC expose multiple Physical Coding Sublayer (PCS) for
the various Serdes port supporting different Media Independent Interface
(10BASE-R, USXGMII, 2500BASE-X, 1000BASE-X, SGMII).

This follow the new PCS provider with the use of #pcs-cells property.

[PATCH net-next v6 12/12] net: airoha: add phylink support

[Christian Marangi]

Add phylink support for each GDM port. For GDM1 add the internal interface
mode as the only supported mode. For GDM2/3/4 add the required
configuration of the PCS to make the external PHY or attached SFP cage
work.

These needs to be defined in the GDM port node using the pcs-handle
property.
