Subject: drm/i915: Get first crtc instead of PIPE_A crtc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: eae3da27ba84a95ade67b03318d7f1f003bd376a
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
intel_plane_fb_max_stride should return the max stride of
primary plane for first available pipe in intel device info
pipe_mask.
Similarly glk_force_audio_cdclk() should also use the first
available CRTC instead of pipe 'A' crtc to force the cdclk
changes.
changes since RFC:
- Introduced a helper to get first intel_crtc intel_get_first_crtc. [Ville]
v1:
- Used intel_get_first_crtc() instead of PIPE_A crtc in
glk_force_audio_cdclk(). [Ville]
