So, Tested-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> I realized that the commit 7ace8fc8219e is not suitable for my environment. (Especially I realized it could use all of DMAC channels when IOMMU was enabled.) So, I will submit RFC patch set for udc-core.c / renesas_usbhs later :) Best regards, Yoshihiro Shimoda -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
