Subject: [PATCH 0/9] Configure GbEth for RGMII on RZ/G2L family

For devices in the RZ/G2L family, we have so far relied on U-Boot correctly
configuring the Ethernet interfaces in RGMII mode with PVDD=1.8V before the
kernel is booted. Instead, the required configuration should be described in the
device tree and activated within the pinctrl driver.

Paul Barker (9):
  pinctrl: renesas: rzg2l: Fix variable names in OEN functions
  pinctrl: renesas: rzg2l: Refactor pin to OEN bit translation
  pinctrl: renesas: rzg2l: Support output enable on RZ/G2L
  arm64: dts: renesas: rzg2l: Enable Ethernet TXC output
  arm64: dts: renesas: rzg2lc: Enable Ethernet TXC output
  arm64: dts: renesas: rzg2ul: Enable Ethernet TXC output
  arm64: dts: renesas: rzg2l: Set Ethernet PVDD to 1.8V
  arm64: dts: renesas: rzg2lc: Set Ethernet PVDD to 1.8V
  arm64: dts: renesas: rzg2ul: Set Ethernet PVDD to 1.8V
