[net-next,v2,00/35,RFT] net: dpaa: Convert to phylink

Message

Sean Anderson June 28, 2022, 10:13 p.m. UTC

This series converts the DPAA driver to phylink. Additionally,
it also adds a serdes driver to allow for dynamic reconfiguration
between 1g and 10g interfaces (such as in an SFP+ slot). These changes
are submitted together for this RFC, but they will eventually be
submitted separately to the appropriate subsystem maintainers.

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 3 for details.

All mac drivers have now been converted. I would greatly appreciate if
anyone has QorIQ boards they can test/debug this series on. I only have an
LS1046ARDB. Everything but QSGMII should work without breakage; QSGMII
needs patch 33.

The serdes driver is mostly functional (but not quite, see patches 5 and
31).  This series only adds support for the LS1046ARDB SerDes, but it
should be fairly straightforward to add support for other SoCs and
boards (see Documentation/driver-api/phy/qoriq.rst). Patches 34 and 25
should show the typical steps.

This patches in this series can be logically categorized as follows:
- 1, 4, 29, 34-35: SerDes support
- 2, 5-25: Cleanups. These can be applied as-is.
- 3, 26-28, 30-33: Phylink conversion

Patches 5-9 were first submitted as [1].

Changes in v2:
- Add #clock-cells. This will allow using assigned-clocks* to configure
  the PLLs.
- Add CGR update function
- Add helper for sanity checking cgr ops
- Add nodes for QSGMII PCSs
- Add rgmii property to all DPAA MACs
- Adjust queue depth on rate change
- Allow a value of 1 for phy-cells. This allows for compatibility with
  the similar (but according to Ioana Ciornei different enough) lynx-28g
  binding.
- Better document how we select which PCS to use in the default case
- Clear SGMIIaCR1_PCS_EN during probe
- Configure the SerDes in enable/disable
- Convert 10GEC and dTSEC as well
- Convert FMan MAC bindings to yaml
- Disable SerDes by default to prevent breaking boards inadvertently.
- Document phy cells in the description
- Document the structure of the compatible strings
- Fix capitalization of mEMAC in commit messages
- Fix example binding having too many cells in regs
- Fix not clearing group->pll after disabling it
- Fix prototype for dtsec_initialization
- Fix warning if sizeof(void *) != sizeof(resource_size_t)
- Handle 1000Base-KX in lynx_proto_mode_prep
- Move PCS_LYNX dependency to fman Kconfig
- Move compatible first
- Power off lanes during probe
- Properly implement all ethtool ops and ioctls. These were mostly
  stubbed out just enough to compile last time.
- Refer to the device in the documentation, rather than the binding
- Remove minItems
- Remove some unused variables
- Remove unused variable slow_10g_if
- Rename LYNX_PROTO_UNKNOWN to LYNX_PROTO_NONE
- Rename driver to Lynx 10G (etc.)
- Rename to fsl,lynx-10g.yaml
- 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.
- Specify type of mac_dev for exception_cb
- Support 1 and 2 phy-cells
- Use list for clock-names
- Use one phy cell for SerDes1, since no lanes can be grouped
