[PATCH RFC 0/3] arm64: dts: qcom: Add Ethernet support for Nord

[PATCH RFC 0/3] arm64: dts: qcom: Add Ethernet support for Nord

[Shawn Guo]

Describe both 10-Gbps Ethernet controllers on Nord and enable them on the
RRD and Ride embedded boards.

The SoC description adds the two EMAC instances (qcom,nord-ethqos) and
their XPCS blocks, plus the SGMII/USXGMII SerDes PHYs they use. Each
controller gets its clocks, reset, power domain, interconnect paths,
SMMU stream IDs and DMA queue configuration.

Patch 2 enables both ports on Nord Ride in fixed-link USXGMII 10 Gbps mode,
for the onboard firmware-driven Ethernet switch. Patch 3 enables both ports
on Nord RRD, each connected over USXGMII to an Aquantia AQR113C PHY on the
controller's MDIO bus, with PHY interrupt and reset GPIOs.

I believe this holds for both GearVM and embedded, so you can move
it to the common DTSI

I think we can't enable the ethernet hosts indiscrimately (I would
love to be corrected here!), can we keep the XPCS nodes enabled by
default?
