Subject: [RFC PATCH 6/8] drm: bridge: analogix_dp: add some rk3288 special registers setting
Date: Thu, 6 Aug 2015 09:22:05 -0500 [thread overview]
Message-ID: <1438870925-23951-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1438868947-22132-1-git-send-email-ykk@rock-chips.com>
RK3288 need some special registers setting, we can separate
them out by the dev_type of plat_data.
