Subject: [PATCH 2/2] video: ipuv3: use non-fractional clock for parallel display
Date: Mon, 12 Nov 2018 17:22:57 +0100 [thread overview]
Message-ID: <20181112162257.2209-2-l.stach@pengutronix.de> (raw)
In-Reply-To: <20181112162257.2209-1-l.stach@pengutronix.de>
There is no need to keep DI and parent clock in sync for the parallel
display interface, but some displays really don't like the jitter
introduced by using a fractional clock.
