Subject: [PATCH v3 7/7] ARM: dts: sun8i: V3: add I2S interface to V3 dts
Date: Fri, 14 May 2021 15:44:05 +0200	[thread overview]
Message-ID: <20210514134405.2097464-8-t.schramm@manjaro.org> (raw)
In-Reply-To: <20210514134405.2097464-1-t.schramm@manjaro.org>

The Allwinner V3 SoC features an I2S interface. The I2S peripheral is
identical to that in the Allwinner H3 SoC.
This commit adds it to the Allwinner V3 dts.
