b8a56e17e1
SH7757 has a USB function with internal DMA controller (SUDMAC). This patch supports the SUDMAC. The SUDMAC is incompatible with general-purpose DMAC. So, it doesn't use dmaengine. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
