From d9facae6afe14f461f0667227c1c377cb84ad7fa Mon Sep 17 00:00:00 2001 From: Shashank Sharma Date: Fri, 12 Oct 2018 11:53:07 +0530 Subject: [PATCH] drm/i915: Introduce CRTC output format MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch adds an enum "intel_output_format" to represent the output format of a particular CRTC. This enum will be used to produce a RGB/YCBCR4:4:4/YCBCR4:2:0 output format during the atomic modeset calculations. V5: - Created this separate patch to introduce and init output_format. - Initialize parameters of output_format_str respectively (Jani N). - Call it intel_output_format than crtc_output_format(Ville). - Set output format in pipe_config for every encoder (Ville). - Get rid of extra DRM_DEBUG_KMS during get_pipe_config (Ville) V6: Rebase V7: Fixed alignment warnings (checkpatch) V8: Another check[atch warning for alignment V9: Rebase V10: Rebase on top of DSI restructure V11: Addressed review comment from Ville - Set CRTC format for pre-HSW get_pipe_config() function too.
