M66592 has the pin of WR0 and WR1. So, if one write-pin of CPU connects to the pins, we have to change the setting of FIFOSEL register in the controller. If we don't change the setting, the controller cannot send the data of odd length. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
