Subject: [PATCH v2 2/2] arm64: dts: meson-gx: add support for simplefb
Date: Mon, 7 Jan 2019 10:53:07 +0100 [thread overview]
Message-ID: <20190107095307.15233-3-mjourdan@baylibre.com> (raw)
In-Reply-To: <20190107095307.15233-1-mjourdan@baylibre.com>
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.
