Subject: [PATCH v6 6/6] drm: exynos: dsi: Switch to atomic funcs
Date: Thu,  3 Mar 2022 22:06:54 +0530	[thread overview]
Message-ID: <20220303163654.3381470-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20220303163654.3381470-1-jagan@amarulasolutions.com>

The new support drm bridges are moving towards atomic functions.

Replace atomic version of functions to continue the transition
to the atomic API.
