We've had some code for quite some time to prevent the alpha bug from happening on the lowest primary plane. Since we now check for this in our atomic_check, we can simply remove it. Reviewed-by:

Now that we have everything in place, we can make zpos configurable now. Change the zpos property from an immutable one to a regular. Reviewed-by:

Maxime Ripard authored
The plane description structure was mostly needed to differentiate the formats usable on the primary plane (because of its lowest position), and assign the pipes. Now that both are dynamically checked and assigned, we can remove the static definition. Reviewed-by:

Maxime Ripard authored
Since we now have a way to enforce the zpos, check for the number of alpha planes, the only missing part is to assign our pipe automatically instead of hardcoding it. The algorithm is quite simple, but requires two iterations over the list of planes. In the first one (which is the same one that we've had to check for alpha, the frontend usage, and so on), we order the planes by their zpos. We can then do a second iteration over that array by ascending zpos starting with the pipe 0. When and if we encounter our alpha plane, we put it and all the other subsequent planes in the second pipe. Reviewed-by:

Move it out of the csv dungeon. While at it add the missing link to the helper functions for setting up the "panel rotation" property. Also OCD how we list enum property values and their corresponding docs. Going for a nest definition list seams cleanest, no need for also making it an uordered list.

Motivated by patch review. The table is really hard to read in source form, hard to edit, and we've moved away to more focused sections about specific features and how they're exposed in properties. Those sections can then more easily enumerate options, link to helper functions and other parts of the docs. All things that get ugly real fast in the docs.

Use the new idr_init_base() function to create an IDR that knows id==0 is never allocated as it maps to an invalid identifier. By knowing that id==0 is invalid, the IDR can start from id=1 instead avoiding the issue of having to start each lookup from the zeroth leaf as id==0 is always unused (and thus the tree-of-bitmaps indicate that is the first available).

When mapping external DMA-bufs through the PRIME mmap call, we might be given an offset which has to be respected. However for the internal DRM GEM mmap path, we have to ignore the fake mmap offset used to identify the buffer only. Currently the code always zeroes out vma->vm_pgoff, which breaks the former. This patch fixes the problem by moving the vm_pgoff assignment to a function that is used only for GEM mmap path, so that the PRIME path retains the original offset.

This commit adds all necessary compatibles and descriptions needed to implement A83T HDMI pipeline. Mixer is already properly described, so only compatible is added. However, A83T TV TCON, which is connected to HDMI, doesn't have channel 0, contrary to all TCONs currently described. Because of that, TCON documentation is extended. A83T features Synopsys DW HDMI controller with a custom PHY which looks like Synopsys Gen2 PHY with few additions. Since there is no documentation, needed properties were found out through experimentation and reading BSP code. At the end, example is added for newer SoCs, which feature DE2 and DW HDMI.
