From 0262f2736978b1763363224698f47112a148dab0 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 6 Mar 2023 09:31:39 +0100 Subject: arm64: dts: amlogic: Add initial support for BPI-CM4 module with BPI-CM4IO baseboard Add support for both the BananaPi BPI-CM4 module and the BananaPi baseboard which is compatible with the RaspberryPi CM4IO baseboard. The BananaPi BPI-CM4 module follows the CM4 specifications at [1], but with a single HDMI port and a single DSI output. The current CM4IO baseboard DT should work fine on the Raspberry CM4 baseboard and other derivatives baseboards, but proper DT should be written for other baseboards. The split is done so it's easy to describe a new CM4 baseboard, enabling only the necessary HW used on the baseboard.
