On the Amlogic Gx SoCs (GXBB, GXL & GXM), the VPU power domain is initialized
by the vendor U-Boot code, but running mainline U-boot has been possible
on these SoCs. But lacking such init made the system lock at kernel boot.
A PM Power Domain driver has been pushed at [1] to solve the main issue.
This patchset depends on the the following patchsets :
- [1] soc: amlogic: add support for Meson GX VPU Domains
- [2] reset: meson: add level reset support for GX SoC family
- [3] clk: meson: gxbb: Add VPU and VAPB clocks
- [4] drm/meson: power domain init related fixes

This patch adds support for the VPU Power Domain nodes, and attaches the
VPU power domain to the VPU node.

On reference boards and derivatives, the HDMI Logic is powered by an external
5V regulator.
This regulator was set by the Vendor U-Boot, add the regulator and phandle
property to the HDMI node.
