[PATCH v4 0/5] Add devicetree features and fixes for UniPhier SoCs

[PATCH v4 0/5] Add devicetree features and fixes for UniPhier SoCs

[Kunihiko Hayashi]

This series adds new features that includes XDMAC for each SoC, ethernet
aliases to inherit MAC address from u-boot, and stabilization for ethernet
on PXs3 ref board.

Changes since v3:
- dt-bindings: Exclude from this series
  The alternative patch fixed by Yamada-san has been applied.
- Fix size of xdmac register region

Changes since v2:
- dt-bindings: Consolidate register description for xdmac
- Spread the size of xdmac register region

Changes since v1:
- dt-bindings: Remove extension register description for xdmac
- Remove extension register area from xdmac node
- Fix commit message for ethernet aliases
- Remove RGMII setting for LD20 global board

These patches in v1 have already been applied:
  ARM: dts: uniphier: Add USB3 controller nodes for Pro5
  arm64: dts: uniphier: Enable spi node for PXs3 reference board
  arm64: dts: uniphier: Add nodes of thermal monitor and thermal zone
    for PXs3
  ARM: dts: uniphier: Set SCSSI clock and reset IDs for each channel
  arm64: dts: uniphier: Set SCSSI clock and reset IDs for each channel

Kunihiko Hayashi (5):
  ARM: dts: uniphier: Add XDMAC node
  arm64: dts: uniphier: Add XDMAC node
  ARM: dts: uniphier: Add ethernet aliases
  arm64: dts: uniphier: Add ethernet aliases
  arm64: dts: uniphier: Stabilize Ethernet RGMII mode of PXs3 ref board

[PATCH v4 3/5] ARM: dts: uniphier: Add ethernet aliases

[Kunihiko Hayashi]

Add an 'aliases' property for ethernet device.

U-boot performs a fix-up of the MAC address and will overwrite the values
from the Linux devicetree for aliased ethernet device. The MAC address can
be inherited from u-boot by adding aliases of ethernet devices.

Re: [PATCH v4 0/5] Add devicetree features and fixes for UniPhier SoCs

[Kunihiko Hayashi]

Sorry for the mistake about the following changes because it was confused
with the other mail. Please wait for xdmac node patches to be reviewed until
the dt-bindings fix patch is available.

Thank you,
