Subject: [PATCH 09/11] drm: bridge: samsung-dsim: Add input_bus_flags
Date: Fri, 8 Apr 2022 21:51:06 +0530 [thread overview]
Message-ID: <20220408162108.184583-10-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20220408162108.184583-1-jagan@amarulasolutions.com>
eLCDIF is expecting to have input_bus_flags as DE_LOW in order to
set active low during valid data transfer on each horizontal line.
Add DE_LOW flag via drm bridge timings.
