[PATCH v4 0/2] Add device tree for NVIDIA VR-NVL BMC

From: Jacky Huang

Date: Tue Jul 28 2026 - 05:24:50 EST


This series adds the DT binding compatible and the device tree for
the NVIDIA VR-NVL BMC, an Aspeed AST2600-based BMC for the Vera
Rubin NVL compute platform.

Changes in v4:
- dts: address dt-check-style findings for property and child node
ordering, required blank lines, and line length.
- dts: retain conventional multi-line block comments, which account
for the remaining 8 mixed-indent findings.
- dts: retain 22 meaningful unused labels for source readability and
future references. They can be removed if preferred.

Changes in v3:
- dts: reword the &mac0 comment per Andrew Lunn's feedback.

Changes in v2:
- dts: correct the compatible of the PDB I/O expander at 0x75 from
nxp,pca9555 to nxp,pca9539 to match the actual part.
- Pick up Acked-by from Krzysztof Kozlowski on the binding.
- Pick up Reviewed-by from Andrew Lunn on the &mac0 and &mdio0 nodes.
