From: Yoshihiro Shimoda yoshihiro.shimoda.uh@renesas.com
commit a58204ab91ad8cae4d8474aa0ba5d1fc504860c9 upstream.
This controller on R-Car Gen3 has 6 pipes that included PIPE 0 for control actually. But, the datasheet has error in writing as it has 31 pipes. (However, the previous code defined 30 pipes wrongly...)
Anyway, this patch fixes it.
