Subject: [PATCH v6 9/9] drm/vc4: hdmi: Enable 10/12 bpc output
Date: Thu, 10 Dec 2020 15:23:29 +0100	[thread overview]
Message-ID: <20201210142329.10640-10-maxime@cerno.tech> (raw)
In-Reply-To: <20201210142329.10640-1-maxime@cerno.tech>

The BCM2711 supports higher bpc count than just 8, so let's support it in
our driver.
