[PATCH 2/2] arm64: dts: meson-gx: add support for simplefb

From: Maxime Jourdan
Date: Mon Dec 10 2018 - 04:06:56 EST


SimpleFB allows transferring a framebuffer from the firmware/bootloader
to the kernel, while making sure the related clocks and power supplies
stay enabled.

Add nodes for CVBS and HDMI Simple Framebuffers.
