Subject: [PATCH 4/9] ARM: dts: stm32: merge spi and i2s nodes
Date: Fri, 19 Nov 2021 15:45:46 +0100 [thread overview]
Message-ID: <20211119144551.7577-5-olivier.moysan@foss.st.com> (raw)
In-Reply-To: <20211119144551.7577-1-olivier.moysan@foss.st.com>
When a SPI instance offers I2S feature, two nodes are defined
in SoC device tree to support both SPI and I2S.
Merge SPI node and I2S nodes into a single node, to avoid
hardware description duplication and compilation warnings.
spi2sx label is used to identify the SPI instances which
are supporting I2S feature.
