charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-amlogic" Errors-To: linux-amlogic-bounces+linux-amlogic=archiver.kernel.org@lists.infradead.org Add support for both the BananaPi BPI-CM4 module and the BananaPi baseboard which is comnpatible with the RaspberryPi CM4IO baseboard. The BananaPi BPI-CM4 module follows the CM4 specifications at [1], but with a single HDMI port and a since 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.
