Subject: [PATCH v6 1/5] dt-bindings: display: add #sound-dai-cells property to rockchip rk3066 hdmi
Date: Sun, 6 Dec 2020 14:33:51 +0100 [thread overview]
Message-ID: <20201206133355.16007-2-jbx6244@gmail.com> (raw)
In-Reply-To: <20201206133355.16007-1-jbx6244@gmail.com>
'#sound-dai-cells' is required to properly interpret
the list of DAI specified in the 'sound-dai' property.
Add it to rockchip,rk3066-hdmi.yaml to document that the
rk3066 HDMI TX also can be used to transmit some audio.
