Subject: [Intel-gfx] [PATCH 07/13] drm/i915/dp: Rearrange check for illegal mode and comments in mode_valid
Date: Fri, 31 Mar 2023 15:46:07 +0530 [thread overview]
Message-ID: <20230331101613.936776-8-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20230331101613.936776-1-ankit.k.nautiyal@intel.com>
Check for MODE_H_ILLEGAL before calculating max rates, lanes etc.
Move comments about compressed bpp U6.4 format closer to where it is used.
