Subject: [PATCH 2/2] ARM: dts: sun8i: r40: Add I2S nodes
Date: Sun, 12 Sep 2021 09:29:14 +0200	[thread overview]
Message-ID: <20210912072914.398419-3-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20210912072914.398419-1-jernej.skrabec@gmail.com>

Allwinner R40 has 3 I2S controllers, compatible to those in H3. First
two are routed to pins, while third is used internally for HDMI audio.

Add nodes for all 3 I2S controllers.
