Oops, current rsnd driver is assuming that DT has all channels. This means it doesn't check src number itself. Can you add src0, 7, 8, 9 with "non exist" comment ? Otherwise, we need to modify driver, but I'm not sure how this assumption is deep. Best regards --- Kuninori Morimoto

Define the generic R8A7794 part of the sound device node. This sound device is a complex one and comprises the Audio Clock Generator (ADG), Sampling Rate Converter Unit (SCU), Serial Sound Interface [Unit] (SSI[U]), and Audio DMAC-Peripheral-Peripheral. It is up to the board file to enable the device. This patch is based on the R8A7791 sound work by Kuninori Morimoto.
