You can skip RK3588 compatible or define it this strictly also for that chip. > >>> + >>> + "#phy-cells": >>> + const: 0 >>> + >>> + resets: >>> + maxItems: 1 >>> + >>> + reset-names: >>> + const: phy >>> + >>> + rockchip,phy-grf: >>> + $ref: /schemas/types.yaml#/definitions/phandle >>> + description: phandle to the syscon managing the phy "general register files" >>> + >>> + rockchip,pipe-grf: >>> + $ref: /schemas/types.yaml#/definitions/phandle >>> + description: phandle to the syscon managing the pipe "general register files" >>> + >>> + rockchip,pcie30-phymode: >>> + $ref: '/schemas/types.yaml#/definitions/uint32' >>> + description: | >>> + use PHY_MODE_PCIE_AGGREGATION if not defined >> >> I don't understand the description.

I got impression you have a header with these values. If yes - mention it here. > use PHY_MODE_PCIE_AGGREGATION (4) as default Just use default as I wrote above. Best regards, Krzysztof
