The current code has info->bufnmb_last to calculate the BUFNMB bits of PIPEBUF register. However, since the bufnmb_last is initialized in the usbhs_pipe_init() only, this driver is possible to set unexpected value to the register if usb_ep_{enable,disable}() are called many times. So, this patch modifies the pipe configuration via struct renesas_usbhs_driver_param to simplify the code. Also this patch changes: - a double buffer configuration - isochronous buffer size from 512 to 1024 Signed-off-by:
