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. Signed-off-by:

Currently the drm/imx/ directory is compiled only if DRM_IMX is set. Adding a new IMX related IP in the same directory would need DRM_IMX to be set, which would bring in also IPUv3 core driver... The current patch would allow adding new IPs in the imx/ directory without needing to set DRM_IMX. Signed-off-by:

Add drm_device argument to drm_prime_pages_to_sg(), so we can call dma_max_mapping_size() to figure the segment size limit and call into __sg_alloc_table_from_pages() with the correct limit. This fixes virtio-gpu with sev. Possibly it'll fix other bugs too given that drm seems to totaly ignore segment size limits so far ... v2: place max_segment in drm driver not gem object. v3: move max_segment next to the other gem fields. v4: just use dma_max_mapping_size().

Drivers using legacy PCI power management .suspend()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

Fixes commit 42ddb453 ("radeon: Conditionally compile PM code") Before the above mentioned patch, codes between the line number 547 and 2803 were already inside "#ifdef CONFIG_PM" container. Thus, addition of "#if defined(CONFIG_PM)" was not required in the patch. It also affected the "#ifdef CONFIG_PPC_OF" container (line 1943-2510). From the current snapshot of radeon_pm.c, remove: 1434 | #if defined(CONFIG_PM) and, 2213 | #endif This removes the redundant CONFIG_PM directive as well as fixes the CONFIG_PPC (earlier CONFIG_PPC_OF) container.
