Subject: [PATCH v5 2/8] drm/omap: Add ovl checking funcs to dispc_ops
Date: Thu, 23 Sep 2021 09:06:55 +0200 [thread overview]
Message-ID: <20210923070701.145377-3-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210923070701.145377-1-narmstrong@baylibre.com>
From: Benoit Parrot <bparrot@ti.com>
In order to be able to dynamically assign overlays to planes we need to
be able to asses the overlay capabilities.
Add a helper function to be able to retrieve the supported capabilities
of an overlay.
And export the function to check if a fourcc is supported on a given
overlay.
