Subject: [PATCH 2/4] drm/tegra: dsi - Handle continuous clock flag
Date: Wed, 2 Jul 2014 21:19:18 +0900 [thread overview]
Message-ID: <1404303560-32209-3-git-send-email-acourbot@nvidia.com> (raw)
In-Reply-To: <1404303560-32209-1-git-send-email-acourbot@nvidia.com>
Handle the MIPI_DSI_MODE_CLOCK_CONTINUOUS flag and only set TX-only
clock behavior when this flag is not present for the DSI device.
