[PATCH 14/15] drm/mediatek: Adjust DRM mode configs for IGT

From: Hsiao Chien Sung
Date: Wed Aug 23 2023 - 11:14:33 EST


IGT (Intel GPU Tool) could commit the following planes
during the test:

kms_plane:

The sub-tests pixel-format-* will create planes with
size of 1 or 4512 pixels, these size will be rejected
by the original mode configs.
Adjust minimum and maximum value of both plane width
and height.

kms_cursor_crc:

If cursor_width and cursor_height is not defined,
IGT uses min_width and min_height as the limitation
when creating cursor plane so sub-tests like
cursor-rapid-movement will be skipped.
Set cursor_width and cursor_height to 512 pixel can
solve the problem.
