2020-11-02drm/amd/display: Keep GSL for full updates with planes that flip VSYNCAlvin Lee
[Why] When enabling PIP in Heaven, the PIP planes are VSYNC flip and is also the top-most pipe. In this case GSL will be disabled because we only check immediate flip for the top pipe. However, the desktop planes are still flip immediate so we should at least keep GSL on until the full update. [How] Check each pipe in the tree to see if any planes are flip immediate. Maintain the GSL lock if yes, and take it down after when unlocking if any planes are flipping VSYNC. Keeping GSL on with VSYNC + flip immediate planes causes corruption.

In these cases, it seems that disconnecting MPCC and doing a surface update at the same time(after unlocking) causes some registers to be updated slightly faster than others after unlocking (e.g. if the pixel format is updated to FP16 before the new surface address is programmed, we get corruption on the screen because the pixel formats aren't matching).
