Subject: [PATCH v7 08/10] drm: bridge: samsung-dsim: Add input_bus_flags
Date: Wed, 5 Oct 2022 20:43:07 +0530 [thread overview]
Message-ID: <20221005151309.7278-9-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20221005151309.7278-1-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.
v7, v6:
* none
v5:
* rebased based on updated bridge changes
v4, v3, v2, v1:
* none
