The Amlogic Meson SoCs embeds a specific Power Domain dedicated to the Video Processing Unit. This patch implements support for this power domain in preparation of the future support for the Video display support in U-Boot.
This driver will depend on changes in the clock driver to handle the setup of the VPU and VAPB clocks configured from DT using assigned-clocks entries.

Hi,
since the driver uses syscon_node_to_regmap() I think the Kconfig entry should also 'select SYSCON'.
