Hi Mark, Rob, Krzysztof Cc Geert Renesas MSIOF can work as both SPI and I2S. Current Linux supports MSIOF-SPI. This patch-set adds new MSIOF-I2S. Because it is using same HW-IP, we want to share same compatible for both MSIOF-SPI/I2S case. MSIOF-I2S (Sound) will use Audio-Graph-Card/Card2 which uses Of-Graph, but MSIOF-SPI is not use Of-Graph. So, this patch-set assumes it was used as MSIOF-I2S if DT is using Of-Graph, otherwise, it is MSIOF-SPI (This assumption will works if SPI *never* use Of-Graph in the future).
