2022-07-29T15:19:20+00:00

[ Upstream commit 02c87df2480ac855d88ee308ce3fa857d9bd55a8 ] In dcss_dev_create() and dcss_dev_destroy(), we should call of_node_put() in fail path or before the dcss's destroy as of_graph_get_port_by_id() has increased the refcount.

drm/imx: Add initial support for DCSS on iMX8MQ

2020-09-09T14:39:48+00:00

This adds initial support for iMX8MQ's Display Controller Subsystem (DCSS). Some of its capabilities include: * 4K@60fps; * HDR10; * one graphics and 2 video pipelines; * on-the-fly decompression of compressed video and graphics; The reference manual can be found here: https://www.nxp.com/webapp/Download?colCode=IMX8MDQLQRM The current patch adds only basic functionality: one primary plane for graphics, linear, tiled and super-tiled buffers support (no graphics decompression yet), no HDR10 and no video planes. Video planes support and HDR10 will be added in subsequent patches once per-plane de-gamma/CSC/gamma support is in.
