Subject: [PATCH 07/18] drm/vc4: hdmi: Add full range RGB helper
Date: Wed, 17 Mar 2021 16:43:41 +0100 [thread overview]
Message-ID: <20210317154352.732095-8-maxime@cerno.tech> (raw)
In-Reply-To: <20210317154352.732095-1-maxime@cerno.tech>
We're going to need to tell whether we want to run with a full or
limited range RGB output in multiple places in the code, so let's create
a helper that will return whether we need with full range or not.
