[PATCH] drm/i915/chv: Update csc coefficient matrix during modeset

[PATCH] drm/i915/chv: Update csc coefficient matrix during modeset

[raviraj.p.sitaram]

From: P Raviraj Sitaram <raviraj.p.sitaram@intel.com>

During modeset, previously configured csc coefficient matrix,if any, will
not persist. This can result in blank screen as csc mode will be programmed
while loading LUT but csc coefficient matrix remains unprogrammed.

No need for the platform check.

Re: [PATCH v10 0/8] YCBCR 4:2:0/4:4:4 output support for LSPCON

[-- Attachment #1.1.1: Type: text/plain, Size: 2799 bytes --]

tested-by: Vania Toperich <Vania@bergehenegouwen.com<mailto:Vania@bergehenegouwen.com>>


This patch series does the following:
- Adds concept of CRTC output format, which indicates if a CRTC is
  driving RGB/YCBCR4:4:4/YCBCR4:2:0 or other outputs.
- Sets RGB as default output for all displays.
- Enables YCBCR4:4:4/4:2:0 outputs for LSPCON displays
- Drives these outputs on LSPCON using this CRTC output framework.

Sharma, Shashank (2):
  drm/i915: Check LSPCON vendor OUI
  drm/i915: Write AVI infoframes for MCA LSPCON

Shashank Sharma (6):
  drm/i915: Introduce CRTC output format
  drm/i915: Add CRTC output format YCBCR 4:2:0
  drm/i915: Add CRTC output format YCBCR 4:4:4
  drm/i915: Add AVI infoframe support for LSPCON
  drm/i915: Write AVI infoframes for Parade LSPCON
  drm/i915: Add YCBCR 4:2:0/4:4:4 support for LSPCON
