Subject: [RFC 03/11] drm/meson: meson_dw_hdmi: switch to drm_bridge_funcs
Date: Tue, 20 Aug 2019 10:41:01 +0200 [thread overview]
Message-ID: <20190820084109.24616-4-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190820084109.24616-1-narmstrong@baylibre.com>
Switch the dw-hdmi driver to drm_bridge_funcs, and add the default supported
YUV444 bus format to the encoder output_bus_caps.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
