Some BCM63268 bootloaders do not enable the internal PHYs by default.
This patch series adds a phy driver to set the registers required
for the gigabit PHY to work.
Currently the PHY can't be detected until the b53 switch is initialized,
but this should be solvable through the device tree. I'm currently
investigating whether the the PHY needs the whole switch to be set up
or just specific clocks, etc.
v2 changes:
- Remove changes to b53 dsa code and rework fix as a PHY driver
- Use a regmap for accessing GPHY control register
- Add documentaion for device tree changes
