Subject: [PATCH 42/59] drm/kmb: Update LCD programming to match MIPI
Date: Tue, 30 Jun 2020 14:27:54 -0700 [thread overview]
Message-ID: <1593552491-23698-43-git-send-email-anitha.chrisanthus@intel.com> (raw)
In-Reply-To: <1593552491-23698-1-git-send-email-anitha.chrisanthus@intel.com>
Mipi input expects the memory layout to be unpacked with 8 bits per
pixel in RGB (BRG) order. If the LCD is not configured properly,
corrupted output results, changed dma_unpacked to 0 in mipi FG.
