Date: Thu, 25 Nov 2021 11:08:34 +0100	[thread overview]
Message-ID: <20211125100836.423808-2-frattaroli.nicolas@gmail.com> (raw)
In-Reply-To: <20211125100836.423808-1-frattaroli.nicolas@gmail.com>

This adds the i2s0 node and an hdmi-sound sound device to the
rk356x device tree. On the rk356[68], the i2s0 controller is
connected to HDMI audio.
