[PATCH net-next v4 0/8] [RFT] net: dpaa: Convert to phylink

[Sean Anderson]

This series converts the DPAA driver to phylink.

I have tried to maintain backwards compatibility with existing device
trees whereever possible. However, one area where I was unable to
achieve this was with QSGMII. Please refer to patch 2 for details.

All mac drivers have now been converted. I would greatly appreciate if
anyone has T-series or P-series boards they can test/debug this series
on. I only have an LS1046ARDB. Everything but QSGMII should work without
breakage; QSGMII needs patches 7 and 8. For this reason, the last 4
patches in this series should be applied together (and should not go
through separate trees).

This series depends on [1] and [2].

Changes in v4:
- Use pcs-handle-names instead of pcs-names, as discussed
- Don't fail if phy support was not compiled in
- Split off rate adaptation series
- Split off DPAA "preparation" series
- Split off Lynx 10G support
- t208x: Mark MAC1 and MAC2 as 10G
- Add XFI PCS for t208x MAC1/MAC2

Changes in v3:
- Expand pcs-handle to an array
- Add vendor prefix 'fsl,' to rgmii and mii properties.
- Set maxItems for pcs-names
- Remove phy-* properties from example because dt-schema complains and I
  can't be bothered to figure out how to make it work.
- Add pcs-handle as a preferred version of pcsphy-handle
- Deprecate pcsphy-handle
- Remove mii/rmii properties
- Put the PCS mdiodev only after we are done with it (since the PCS
  does not perform a get itself).
- Remove _return label from memac_initialization in favor of returning
  directly
- Fix grabbing the default PCS not checking for -ENODATA from
  of_property_match_string
- Set DTSEC_ECNTRL_R100M in dtsec_link_up instead of dtsec_mac_config
- Remove rmii/mii properties
- Replace 1000Base... with 1000BASE... to match IEEE capitalization
- Add compatibles for QSGMII PCSs
- Split arm and powerpcs dts updates

Changes in v2:
- Better document how we select which PCS to use in the default case
- Move PCS_LYNX dependency to fman Kconfig
- Remove unused variable slow_10g_if
- Restrict valid link modes based on the phy interface. This is easier
  to set up, and mostly captures what I intended to do the first time.
  We now have a custom validate which restricts half-duplex for some SoCs
  for RGMII, but generally just uses the default phylink validate.
- Configure the SerDes in enable/disable
- Properly implement all ethtool ops and ioctls. These were mostly
  stubbed out just enough to compile last time.
- Convert 10GEC and dTSEC as well
- Fix capitalization of mEMAC in commit messages
- Add nodes for QSGMII PCSs
- Add nodes for QSGMII PCSs

[PATCH net-next v4 2/8] dt-bindings: net: fman: Add additional interface properties

[Sean Anderson]

At the moment, mEMACs are configured almost completely based on the
phy-connection-type. That is, if the phy interface is RGMII, it assumed
that RGMII is supported. For some interfaces, it is assumed that the
RCW/bootloader has set up the SerDes properly. This is generally OK, but
restricts runtime reconfiguration. The actual link state is never
reported.

To address these shortcomings, the driver will need additional
information. First, it needs to know how to access the PCS/PMAs (in
order to configure them and get the link status). The SGMII PCS/PMA is
the only currently-described PCS/PMA. Add the XFI and QSGMII PCS/PMAs as
well. The XFI (and 10GBASE-KR) PCS/PMA is a c45 "phy" which sits on the
same MDIO bus as SGMII PCS/PMA. By default they will have conflicting
addresses, but they are also not enabled at the same time by default.
Therefore, we can let the XFI PCS/PMA be the default when
phy-connection-type is xgmii. This will allow for
backwards-compatibility.

QSGMII, however, cannot work with the current binding. This is because
the QSGMII PCS/PMAs are only present on one MAC's MDIO bus. At the
moment this is worked around by having every MAC write to the PCS/PMA
addresses (without checking if they are present). This only works if
each MAC has the same configuration, and only if we don't need to know
the status. Because the QSGMII PCS/PMA will typically be located on a
different MDIO bus than the MAC's SGMII PCS/PMA, there is no fallback
for the QSGMII PCS/PMA.

[PATCH net-next v4 7/8] powerpc: dts: qoriq: Add nodes for QSGMII PCSs

[Sean Anderson]

Now that we actually read registers from QSGMII PCSs, it's important
that we have the correct address (instead of hoping that we're the MAC
with all the QSGMII PCSs on its bus). This adds nodes for the QSGMII
PCSs. They have the same addresses on all SoCs (e.g. if QSGMIIA is
present it's used for MACs 1 through 4).

Since the first QSGMII PCSs share an address with the SGMII and XFI
PCSs, we only add new nodes for PCSs 2-4. This avoids address conflicts
on the bus.

[PATCH net-next v4 8/8] arm64: dts: layerscape: Add nodes for QSGMII PCSs

[Sean Anderson]

Now that we actually read registers from QSGMII PCSs, it's important
that we have the correct address (instead of hoping that we're the MAC
with all the QSGMII PCSs on its bus). This adds nodes for the QSGMII
PCSs.  The exact mapping of QSGMII to MACs depends on the SoC.

Since the first QSGMII PCSs share an address with the SGMII and XFI
PCSs, we only add new nodes for PCSs 2-4. This avoids address conflicts
on the bus.

ping?

This will not apply on net-next/master, so I will resend sometime soon,
but does anyone have any feedback first?
