Subject: [PATCH 03/26] drm/rockchip: dw-mipi-dsi: don't configure hardware in mode_set for MIPI
Date: Mon, 19 Sep 2016 18:17:13 +0100	[thread overview]
Message-ID: <20160919171747.28512-4-john@metanate.com> (raw)
In-Reply-To: <20160919171747.28512-1-john@metanate.com>

With atomic modesetting the hardware will be powered off when the
mode_set function is called.  We should configure the hardware in the
commit function (or even the enable function, but switching from commit
to enable is left for a future patch).
