Ran into one complaint from dtbs_check:
arch/riscv/boot/dts/renesas/r9a07g043f01-smarc.dtb: usb-phy@11c50200: '#phy-cells' is a required property
From schema: /home/conor/.local/lib/python3.10/site-packages/dtschema/schemas/phy/phy-provider.yaml
arch/riscv/boot/dts/renesas/r9a07g043f01-smarc.dtb: usb-phy@11c70200: '#phy-cells' is a required property
From schema: /home/conor/.local/lib/python3.10/site-packages/dtschema/schemas/phy/phy-provider.yaml
Other than that which should be a trivial fix the whole lot looks good
to me...
