Subject: [PATCH 8/8] video: tc358767: accept any hsync and vsync polatiry
Date: Fri, 30 Jun 2017 14:43:04 +0300 [thread overview]
Message-ID: <20170630114304.8070-9-andrey.gusakov@cogentembedded.com> (raw)
In-Reply-To: <20170630114304.8070-1-andrey.gusakov@cogentembedded.com>
Do not fix modes. Instead set any sync polarity passed through
VPL_PREPARE and fb_videomode.
