Subject: [PATCH v1 7/8] drm: rockchip: analogix_dp: correct the connector display color format and bpc
Date: Mon, 25 Apr 2016 19:38:32 +0800	[thread overview]
Message-ID: <1461584312-6297-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1461583748-5777-1-git-send-email-ykk@rock-chips.com>

Rockchip VOP couldn't output YUV video format for eDP controller, so
when driver detect connector support YUV video format, we need to hack
it down to RGB888.
