Hi Frank,
Combine your patch in a serie with Rockchip rk356x sata nodes and
include all current CC people and Rockchip list.
Your conversion and DT patch contains lots of errors.
Check your serie with all/more platforms then Rockchip before you submit
and fix.
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make dt_binding_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/ata/ahci-platform.yaml
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/ata/ahci-platform.yaml
Add power-domains as a new property after the conversion patch.

A node without clocks does that work?
Shouldn't that be required?

Already in included sata-common.yaml
"^sata-port@[0-9a-e]$":
How many ports does this thing support??
