The A733 PCK600, similar to A523 PCK600, is likely a customized version of ARM PCK-600 power controller. They share the same BSP drivers in the package provided by Radxa, with the only difference being the lack of resets. Therefore, document A733 compatible and make resets required only for the other models, as well as prepare the PD definitions for future device trees.
