Dear Greg
These are DMAEngine support for renesas_usbhs
Kuninori Morimoto (13):
usb: renesas_usbhs: modify pipe direction flags
usb: renesas_usbhs: fifo became independent from pipe.
usb: renesas_usbhs: divide data transfer functions
usb: renesas_usbhs: modify packet queue control method
usb: renesas_usbhs: modify data transfer method
usb: renesas_usbhs: modify data transfer interrupt
usb: renesas_usbhs: remove usbhsg_queue_get
usb: renesas_usbhs: shrink spin lock area
usb: renesas_usbhs: add usbhsf_fifo
usb: renesas_usbhs: add pipe/fifo link
usb: renesas_usbhs: tifyup packet start timing
usb: renesas_usbhs: tidyup pio handler name
usb: renesas_usbhs: add DMAEngine support
Last patch adds DMAEngine code to renesas_usbhs,
but it is still using PIO.~~~~
(it is easy to change PIO -> DMA. see below)
Because there are 2type of USB DMAC on SuperH chip.
1st type is "USB DMA on normal DMAC",
and 2nd type is "USB-DMAC".
These 2 DMAC have a little bit different behavior.
This patch adds 1st type DMAC code.
The both DMA will be formally supported in the future.
I tested this DMAEngine for 1st DMAC - renesas_usbhs on SH7724 Ecovec board.
It is easy to enable DMAEngine by local fixup for now.
usbhs_fifo_pio_push_handler -> usbhs_fifo_dma_push_handler
usbhs_fifo_pio_pop_handler -> usbhs_fifo_dma_pop_handler
on usbhsg_ep_enable.
Best regards
