Subject: [PATCH v5 09/11] drm/mediatek: add hdmi driver for MT2701 and MT7623
Date: Wed, 3 Oct 2018 11:41:49 +0800 [thread overview]
Message-ID: <20181003034151.31452-10-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20181003034151.31452-1-bibby.hsieh@mediatek.com>
From: chunhui dai <chunhui.dai@mediatek.com>
This patch adds hdmi dirver suppot for both MT2701 and MT7623.
And also support other (existing or future) chips that use
the same binding and driver.
