There is a lot of code related with PHY part of the mt7621 PCI driver
that can be extracted to a new PHY generic driver to do the same function.
This patch series add a new 'mt7621-pci-phy' driver to handle those
and updates the mt7621-pci driver code to use generic kernel's PHY
API. This makes the code much better and readable.
Device tree has been also updated with new related bindinds for the
PCI PHY part.
This changes are only compile-tested.
Changes in v3:
- Change '#phy-cells' to be zero instead of one avoiding to implement
custom 'xlate' function in phy's driver. All of phy types for the
phy driver are 'PHY_TYPE_PCIE' which is for that the '#phy-cells'
was using for. There is no sense to check the type in a custom 'xlate' function.
Phy's driver 'mt7621_pci_phy_xlate' has been deleted and now the generic
'of_phy_simple_xlate' is being used.
- Update MODULE_LICENSE to use 'GPL v2' instead of 'GPL'.
- Add kernel doc for phy's driver data structures.
- Add a PATCH with DT bindings documentation.
Changes in v2:
- PATCH 1: remap registers first and assign virtual address after
for each port because they share the same address space.
Hope this helps.
Thanks in advance.
Best regards,
