Subject: [PATCH v4 1/4] drm/mediatek: Add AAL engine basic function
Date: Thu, 28 Jul 2016 10:22:52 +0800 [thread overview]
Message-ID: <1469672575-5847-2-git-send-email-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <1469672575-5847-1-git-send-email-bibby.hsieh@mediatek.com>
In order to correct brightness values, we have
to support gamma funciton on MT8173. In MT8173,
we have two engines for supporting gamma function:
AAL and GAMMA. This patch add some AAL engine
basic function, include config, start and stop
function.
