Subject: [PATCH 27/36] drm/pl111: use bpp instead of cpp for drm_format_info
Date: Mon, 23 Sep 2019 20:53:00 +0800 [thread overview]
Message-ID: <1569243189-183445-2-git-send-email-hjc@rock-chips.com> (raw)
In-Reply-To: <1569243189-183445-1-git-send-email-hjc@rock-chips.com>
cpp[BytePerPlane] can't describe the 10bit data format correctly,
So we use bpp[BitPerPlane] to instead cpp.
