This series adds MediaTek hardware support for CTM (Color Transformation
Matrix) color tests.

MediaTek display hardware has two specific characteristics for CTM:
1. CTM matrix value range is limited to -2.0 to 2.0
2. Bit-true results are only achievable with 10-bit color depth

Patch 1 clamps CTM matrix values to the hardware-supported range to
prevent test failures when values exceed the limits.

Patch 2 switches to 10-bit color depth and XRGB2101010 format for
MediaTek devices to enable accurate CRC validation.

Jason-JH Lin (2):
  test/kms_color: Clamp CTM values to -2.0~2.0 for MediaTek devices
  tests/kms_color: Add 10-bit color depth support to CTM test for
    MediaTek
