However, table 7A.12 still lists the SRC0/7/8/9 clocks for > R8A7794, table 11.1 still lists SRC0/7/8/9 interrupts for R8A7794, and > table 43.4 still lists SRC0/7/8/9 MID+RID for R8A7794 -- go figure...
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
