From: Dmitry Baryshkov Date: Sat, 15 Apr 2023 17:19:25 +0000 (+0300) Subject: drm/msm/dpu: simplify intf allocation code X-Git-Tag: v6.6.17~3937^2~4^2~176^3~67 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5a7a86bfa2cd79c80e4f3bdb01feb15edd08b92b;p=platform%2Fkernel%2Flinux-rpi.git drm/msm/dpu: simplify intf allocation code Rather than passing DRM_MODE_ENCODER_* and letting dpu_encoder to guess, which intf type we mean, pass INTF_DSI/INTF_DP directly. This is required to support HDMI output in DPU, as both DP and HDMI encoders are DRM_MODE_ENCODER_TMDS. Thus dpu_encoder code can not make a difference between HDMI and DP outputs.
