Subject: [PATCH 03/26] video: of: display_timing: Add support for syncclk-active property
Date: Thu, 1 Sep 2016 14:22:57 +0300	[thread overview]
Message-ID: <20160901112320.15246-4-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20160901112320.15246-1-peter.ujfalusi@ti.com>

Configure the DISPLAY_FLAGS_SYNC_POSEDGE/NEGEDGE flags according to the
binding document.
If the syncclk-active is present in DT, configure the flags accordingly, if
it is omitted it means that the SYNC edge is following the pixdata
configuration.
