Subject: [PATCH 2/2] arm64: dts: meson-gx: add support for simplefb
Date:   Mon, 10 Dec 2018 10:06:40 +0100
Message-Id: <20181210090640.4495-2-mjourdan@baylibre.com>

Precedence: bulk

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.
