How can you predict all names? > Based on the datasheet, the SoC(s) have the following naming conventions: - sama7g5: I2SMCC0 and I2SMCC1 - sam9x60/sam9x75: I2SMCC To accommodate these variations, I propose using a more relaxed pattern: "^I2SMCC(0-9)?$". This pattern allows for both the fixed prefix and an optional single digit at the end.

In the current file, I have referenced `dai-common` as shown here: https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/sound/microchip%2Csama7g5-i2smcc.yaml#L74C1-L75C27 Could you please confirm if this reference is correctly implemented, or suggest any adjustments needed to align with the common schema?
