2024-08-13drm/amd/display: Adjust cursor positionRodrigo Siqueira
[why & how] When the commit 9d84c7ef8a87 ("drm/amd/display: Correct cursor position on horizontal mirror") was introduced, it used the wrong calculation for the position copy for X. This commit uses the correct calculation for that based on the original patch.

2024-08-13drm/amd/display: fix cursor offset on rotation 180Melissa Wen
[why & how] Cursor gets clipped off in the middle of the screen with hw rotation 180. Fix a miscalculation of cursor offset when it's placed near the edges in the pipe split case. Cursor bugs with hw rotation were reported on AMD issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/2247 The issues on rotation 270 was fixed by: https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/ that partially addressed the rotation 180 too. So, this patch is the final bits for rotation 180.
