[PATCH v2 00/23] arm64: qcom: sa8775p-ride: enable the first ethernet port

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

There are three ethernet ports on sa8775p-ride. This series contains changes
required to enable one of the two 1Gb ports (the third one is 10Gb). We need
to add a new driver for the internal SerDes PHY, introduce several extensions
to the MAC driver (while at it: tweak coding style a bit etc.) and finally
add the relevant DT nodes.

v1 -> v2:
- move the phy-supply property from the MAC driver over to the SerDes PHY
  driver
- rework the SerDes PHY driver to work with the correct ordering of phy
  operations (init -> power_on -> set_speed)
- change the serdes_phy node label to serdes0 to be in line with other DT
  sources and make it ready for the second PHY instance
- dropped the status property from the example in SerDes PHY's DT bindings
  and moved properties around
- reworked the fourth clock in the ethqos driver: it's handled the same
  whether it's called rgmii or phyaux
- other minor tweaks
- use 0x0 consistently in DT
- squash dwmac and ethqos-specific bindings changes
- collected tags
