Subject: [PATCH 0/4] drm/meson: power domain init related fixes

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.
The following patches :
- updates the DT bindings accordingly
- adds support for missing regulators and registers init

Neil Armstrong (4):
  dt-bindings: display: amlogic,meson-vpu: Add optional power domain
    property
  dt-bindings: display: amlogic,meson-dw-hdmi: Add optional HDMI 5V
    regulator
  drm/meson: dw_hdmi: Add support for an optional external 5V regulator
  drm/meson: Add missing VPU init
