[PATCH 0/3] drm: Test for primary plane in new drm_atomic_helper_check_crtc_state()

[Thomas Zimmermann]

Provide drm_atomic_helper_check_crtc_state() for validating a CRTC
state against common constraints. As many CRTC need a primary plane
to work correctly, add this as the first test.

The simple-KMS helpers already contain related code. Convert it
to the new helper. Also add this test to ast.

The simple-kms changes were tested with simpledrm. The ast changes
were tested in AST2300 hardware.

Thomas Zimmermann (3):
  drm/atomic-helper: Add helper drm_atomic_helper_check_crtc_state()
  drm/simple-kms: Use drm_atomic_helper_check_crtc_state()
  drm/ast: Enable primary plane with CRTC
