Subject: [PATCHv2 1/7] drm/bridge: tc358767: add bus flags
Date: Thu, 3 Jan 2019 13:59:48 +0200 [thread overview]
Message-ID: <20190103115954.12785-2-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20190103115954.12785-1-tomi.valkeinen@ti.com>
tc358767 driver does not set DRM bus_flags, even if it does configures
the polarity settings into its registers. This means that the DPI source
can't configure the polarities correctly.
Add sync flags accordingly.
