This series seem to handle the RV1103B variant and not the RV1106/RV1103
variant, please name parts as rv1103b to match vendor U-Boot or is the
rv1106/rv1103 and rv1103b fully compatible?

For the Rockchip platform we typically expect e.g. dt-bindings headers
for core parts to be upstreamed to Linux and picked from dts/upstream
for new SoC support.

Please at least send out clk and pinctrl dt-bindings and drivers for
Linux before a v2 of this series :-)
