2013-01-22usb: Convert to devm_ioremap_resource()Thierry Reding1-5/+4
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

current mod_gadget had got usb speed on usbhsg_irq_dev_state() which is status change interrupt callback function. And the usb speed data was included in its parameter.

USB DMA was installed on "normal DMAC" when SH7724 or older SuperH, but the "USB-DMAC" was prepared on recent SuperH. These 2 DMAC have a little bit different behavior. This patch add DMAEngine code for "normal DMAC", but it is still using PIO fifo. The DMA fifo will be formally supported in the future. You can enable DMA fifo by local fixup usbhs_fifo_pio_push_handler -> usbhs_fifo_dma_push_handler usbhs_fifo_pio_pop_handler -> usbhs_fifo_dma_pop_handler on usbhsg_ep_enable.
