drm/imx/dcss: stop using drm_bridge_connector_en/disable_hpd()

2023-01-05T14:07:01Z

The functionality of drm_bridge_connector_enable_hpd() and drm_bridge_connector_disable_hpd() is provided automatically by the drm_kms_poll helpers. Stop calling these functions manually.

drm: imx/dcss: Remove #ifdef guards for PM related functions

2022-12-12T13:07:01Z

Use the EXPORT_GPL_DEV_PM_OPS() and pm_ptr() macros to handle the PM callbacks. These macros allow the PM functions to be automatically dropped by the compiler when CONFIG_PM is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

drm/imx/dcss: Add missing of_node_put() in fail path

2022-07-20T07:12:15Z

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

2020-09-09T14:39:48Z

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.
