Subject: [PATCH v5 0/3] Add basic SPI support for SOPHGO SG2042 SoC
Date: Tue, 22 Apr 2025 10:27:07 +0800 [thread overview]
Message-ID: <20250422-sfg-spi-v5-0-c7f6554a94a0@gmail.com> (raw)
Implemented basic SPI support for SG2042 SoC[1] using
the upstreamed Synopsys DW-SPI IP.
The way of testing can be found here [2].
