Subject: [PATCH v3 0/3] net: phy: bcm63xx: add support for BCM63268 GPHY

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. 

v3 changes:
- Remove syscon for the GPHY control register
- Change driver to access the GPIO controller syscon
- Move syscon phandle from mdio bus to phy node
- Remove unecessary devm_phy_package_join()
- Made functions static to fix build warning
- Fix formatting and whitespace issues
- Add schema for PHY driver
- Deassert PHY reset signal 

v2: https://lore.kernel.org/netdev/d819144d-ce2f-4ea5-8bfb-83e341672da6@gmail.com/
- 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
