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.
There is one issue which makes the new driver not as clean as I would
like to be which is the fact that pcie0_port and pcie1_port share the
same address space for its registers and only differ en enable bit for
the phy. Because of this, we cannot remap the register address space twice.
The function 'probe' of the driver take this into consideration to not
fail if port is '1' which is not a good way to go, but I cannot find similar
sample or another way to go. It would be nice if someone could point me
out in the correct way.
This changes are only compile-tested.
Hope this helps.
Thanks in advance.
