[PATCH v2 1/5] dt-bindings: net: renesas,etheravb: Add r8a779a0 support

[Wolfram Sang]

Document the compatible value for the RAVB block in the Renesas R-Car
V3U (R8A779A0) SoC. This variant has no stream buffer, so we only need
to add the new compatible and add it to the TX delay block.

Please apply via netdev tree.

Change since v1:
* add entry to TX delay block
* added tags

[PATCH v2 3/5] arm64: dts: renesas: r8a779a0: Add Ethernet-AVB support

[Wolfram Sang]

From: Tho Vu <tho.vu.wh@renesas.com>

Define the generic parts of Ethernet-AVB device nodes. Only AVB0 was
tested because it was the only port with a PHY on current hardware.

* added alias for avb0 so firmware can add MAC address
* added custom tx-internal-delay-ps
* dropped '_tx' suffix from 'pins_mii' config
* moved entries to Falcon CPU dtsi

[PATCH v2 5/5] WIP! arm64: dts: renesas: falcon: Add Ethernet-AVB1-5 support

[Wolfram Sang]

PHYs on the subboard could not be reached via remote access. But this is
the latest DTS snipplet with some fixes suggested by Geert as a starting
point. Not for upstream yet!
