Subject: [PATCH v3 3/3] arm64: dts: cix: add a compatible string for the cix sky1 SoC
Date: Fri, 31 Oct 2025 15:30:03 +0800 [thread overview]
Message-ID: <20251031073003.3289573-4-jun.guo@cixtech.com> (raw)
In-Reply-To: <20251031073003.3289573-1-jun.guo@cixtech.com>
The SPI IP design for the cix sky1 SoC uses a FIFO with a data width
of 32 bits, instead of the default 8 bits. Therefore, a compatible
string is added to specify the FIFO data width configuration for the
cix sky1 SoC.
