usb: renesas_usbhs: add R-Car Gen3 power control

2016-03-04T13:14:28+00:00

Since the usb2 phy driver for gen3 (phy-rcar-gen3-usb2) cannot access
LPSTS and UGCTRL2 registers in the HSUSB module, this driver have to
initialize the registers. So, this patch adds such handling code into
rcar3.c.

usb: renesas_usbhs: Modify pipe configuration

2015-12-15T15:12:41+00:00

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

usb: renesas_usbhs: fix build warning if 64-bit architecture

2015-09-30T16:21:03+00:00

This patch fixes the following warning if 64-bit architecture environment:

usb: renesas_usbhs: Change USBHS_TYPE_R8A779x to USBHS_TYPE_RCAR_GEN2

2015-05-26T15:39:39+00:00

Since the HSUSB controllers of R-Car Gen2 are the same specification
(they have 16 pipes and usb-dmac), this patch changes USBHS_TYPE_R8A7790
and USBHS_TYPE_R8A7791 to USBHS_TYPE_RCAR_GEN2.

usb: renesas_usbhs: add support for USB-DMAC

2015-03-13T15:41:19+00:00

Some Renesas SoCs have the USB-DMAC. It is able to terminate transfers
when a short packet is received, even if less bytes than the transfer
counter size have been received. Also, it is able to send a short
packet even if the packet size is not multiples of 8bytes.

Since the previous code has used the interruption of USBHS controller
when receiving packets even if this driver has used a dmac, a lot of
interruptions has happened. This patch will reduce such interruptions.

This patch allows to use the USB-DMAC on R-Car H2 and M2.

usb: renesas_usbhs: expand USB-DMAC channels for R-Car Gen2

2014-11-12T15:11:31+00:00

This patch expands USB-DMAC channels for R-Car Gen2 SoCs. The SoCs
have 4 channels. If d{2,3}_{t,x}x_id are not set, this driver never
uses the expanded USB-DMAC channels.

usb: renesas_usbhs: add DMAEngine ID specification note

2012-06-13T19:38:36+00:00

renesas_usbhs DMAEngine uses D0FIFO/D1FIFO,
but the data transfer direction should be fixed for keeping consistency.

usb: renesas_usbhs: add support for SUDMAC

2012-01-24T09:33:04+00:00

The SUDMAC uses 8-bit width only. So, when the driver uses SUDMAC,
we have to clear the MBW_32.
