2024-02-02drm/imx/dcss: have all init functions use devresPhilipp Stanner1-1/+0
dcss currently allocates and ioremaps quite a few resources in its probe function's call graph. Devres now provides convenient functions which perform the same task but do the cleanup automatically. Port all memory allocations and ioremap() calls to the devres counterparts.

2022-12-12drm: imx/dcss: Remove #ifdef guards for PM related functionsPaul Cercueil1-4/+3
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.

2020-11-26drm/imx/dcss: allow using nearest neighbor interpolation scalingLaurentiu Palcu1-0/+3
This patch adds support for using NN interpolation scaling by setting the SCALING_FILTER plane property to 1. Otherwise, the default method is used.

2020-09-09drm/imx: Add initial support for DCSS on iMX8MQLaurentiu Palcu1-0/+177
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.
