Subject: [PATCH 00/26] arm64: qcom: sa8775p-ride: enable the first ethernet port

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

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.

Bartosz Golaszewski (26):
  phy: qualcomm: fix indentation in Makefile
  dt-bindings: phy: describe the Qualcomm SGMII PHY
  phy: qcom: add the SGMII SerDes PHY driver
  arm64: defconfig: enable the SerDes PHY for Qualcomm DWMAC
