[PATCH v2 0/5] phy: core: rework phy_set_mode to accept phy mode and submode

[Grygorii Strashko]

Hi Kishon, All,

As was discussed in [1] I'm posting series which introduces rework of
phy_set_mode to accept phy mode and submode. I've dropped TI specific patches as
this change is pretty big by itself.

Patch 1 is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

Patches 2-4: Add new PHY's mode to be used by Ethernet PHY interface drivers or
multipurpose PHYs like serdes and convert ocelot-serdes and mvebu-cp110-comphy
PHY drivers to use recently introduced PHY_MODE_ETHERNET and phy_set_mode_ext().

Patch 5 - removes unused, ethernet specific phy modes from enum phy_mode.

Testing:
 - series tested on TI am335x/am437x/am5(dra7) paltforms.
 - other driver build tested.

changes in v2:
- marvell PHY and net drivers updated as recommended by Russell King

[PATCH v2 1/5] phy: core: rework phy_set_mode to accept phy mode and submode

[Grygorii Strashko]

Currently the attempt to add support for Ethernet interface mode PHY
(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
duplicate there values from phy_interface_t enum (or introduce more PHY
callbacks) [1]. Both approaches are ineffective and would lead to fast
bloating of enum phy_mode or struct phy_ops in the process of adding more
PHYs for different subsystems which will make them unmaintainable.

As discussed in [1] the solution could be to introduce dual level PHYs mode
configuration - PHY mode and PHY submode. The PHY mode will define generic
PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
specific interface mode. The last is usually already defined in
corresponding subsystem headers (phy_interface_t for Ethernet, enum
usb_device_speed for USB).

This patch is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

[PATCH v2 1/5] phy: core: rework phy_set_mode to accept phy mode and submode

[Grygorii Strashko]

Currently the attempt to add support for Ethernet interface mode PHY
(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
duplicate there values from phy_interface_t enum (or introduce more PHY
callbacks) [1]. Both approaches are ineffective and would lead to fast
bloating of enum phy_mode or struct phy_ops in the process of adding more
PHYs for different subsystems which will make them unmaintainable.

As discussed in [1] the solution could be to introduce dual level PHYs mode
configuration - PHY mode and PHY submode. The PHY mode will define generic
PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
specific interface mode. The last is usually already defined in
corresponding subsystem headers (phy_interface_t for Ethernet, enum
usb_device_speed for USB).

This patch is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

[PATCH v2 1/5] phy: core: rework phy_set_mode to accept phy mode and submode

[Grygorii Strashko]

Currently the attempt to add support for Ethernet interface mode PHY
(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
duplicate there values from phy_interface_t enum (or introduce more PHY
callbacks) [1]. Both approaches are ineffective and would lead to fast
bloating of enum phy_mode or struct phy_ops in the process of adding more
PHYs for different subsystems which will make them unmaintainable.

As discussed in [1] the solution could be to introduce dual level PHYs mode
configuration - PHY mode and PHY submode. The PHY mode will define generic
PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
specific interface mode. The last is usually already defined in
corresponding subsystem headers (phy_interface_t for Ethernet, enum
usb_device_speed for USB).

This patch is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

Thanks for the patch, it's annoying to have to map PHY_MODE_SGMII and
PHY_INTERFACE_MODE_SGMII :)

This works for now because we only support Ethernet muxes for now but
this IP also supports PHY_MODE_PCIE.

It seems weird to me that the day we'll add support for PCIE muxing we
will have in ocelot_serdes_muxes[i].mode either a PHY_INTERFACE_MODE_*
or a PHY_MODE_PCIE. This is not an issue for now since you do the mode
!= PHY_MODE_ETHERNET just above but once we get rid of this, we only
test for submode != ocelot_serdes_muxes[i].mode and both
PHY_INTERFACE_MODE_1000BASEX and PHY_MODE_PCIE will have the same index
thus might be confused.

Should we add a submode to the SERDES_MUX macro, move PHY_MODE_*MII to
this submode and have PHY_MODE_ETHERNET/PCIE in the mode field?

Thanks,
Quentin

It seems weird to me that the day we'll add support for PCIE muxing we
will have in ocelot_serdes_muxes[i].mode either a PHY_INTERFACE_MODE_*
or a PHY_MODE_PCIE. This is not an issue for now since you do the mode

test for submode != ocelot_serdes_muxes[i].mode and both
PHY_INTERFACE_MODE_1000BASEX and PHY_MODE_PCIE will have the same index
thus might be confused.

Should we add a submode to the SERDES_MUX macro, move PHY_MODE_*MII to
this submode and have PHY_MODE_ETHERNET/PCIE in the mode field?

Thanks,

Yeh. You are right. I'll update it this way.

[PATCH v2 4/5] phy: mvebu-cp110-comphy: convert to use eth phy mode and submode

[Grygorii Strashko]

Convert mvebu-cp110-comphy PHY driver to use recently introduced
PHY_MODE_ETHERNET and phy_set_mode_ext().

Sorry I missed your V2, hopefully I tested the right version this time.
Tested on MCBin, this works just fine.

Thanks,

Sorry I missed your V2, hopefully I tested the right version this time.
Tested on MCBin, this works just fine.

Thanks,

Sorry I missed your V2, hopefully I tested the right version this time.
Tested on MCBin, this works just fine.

Sorry I missed your V2, hopefully I tested the right version this time.
Tested on MCBin, this works just fine.

Thanks,

Thank you for review. I seems need to update it same way as requested
for ocelot-serdes by Quentin Schulz and add pair mode + submode handling
where needed. Will update and re-send.

[PATCH v2 5/5] phy: core: clean up unused ethernet specific phy modes

[Grygorii Strashko]

After recent changes PHY_MODE_SGMII, PHY_MODE_2500SGMII, PHY_MODE_QSGMII,
PHY_MODE_10GKR are not used any more and can be removed. Hence - remove
them.
