This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbhs is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,rcar-gen2-usbhs". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.

For the case where an external VBUS is used, we should enable the external VBUS comparator in the driver. This would prevent an unnecessary overcurrent error which would then disable the host port. This patch uses the standard 'disable-over-current' binding to allow of the option of disabling the over-current condition.

When set otg_sel(SSUSB_U2_PORT_OTG_SEL) for u2port which supports dual-role mode, the controller will automatically switch mode between host and device according to IDDIG signal. But if the u2port only supports device mode, and no IDDIG pin is provided, setting otg_sel may cause failure of detection by host. So set it only for dual-role mode.

When dr_mode is set as USB_DR_MODE_HOST, it's better to try to get optional vbus, this can increase flexibility, although we can set vbus as always on for regulator or put it in host driver to turn it on.

Use the of_device_get_match_data() helper instead of open coding, postponing the matching until when it's really needed. Note that the renesas_usb3 driver is used with DT only, so there's always a valid match.

This patch adds support for R-Car D3. This SoC needs to release the PLL reset by the UGCTRL register.

The dummy-hcd driver doesn't support emulation of isochronous transfers. Therefore it doesn't need to export isochronous endpoint descriptors; they can be commented out. Also, the comments in the source code don't express clearly enough the fact that isochronous isn't supported. They need to be more explicit. Finally, change the error status value we use (in theory) for isochronous URBs. checkpatch complains about ENOSYS; EINVAL is more appropriate (it is documented to mean "ISO madness").

Part of the emulation performed by dummy-hcd is accounting for bandwidth utilization. The total amount of data transferred in a single frame is supposed to be no larger than an actual USB connection could accommodate. Currently the driver performs bandwidth limiting only for bulk transfers; control and periodic transfers are effectively unlimited. (Presumably drivers were not expected to request extremely large control or interrupt transfers.) This patch improves the situation somewhat by restricting them as well. The emulation still isn't perfect. On a real system, even 0-length transfers use some bandwidth because of transaction overhead (IN, OUT, ACK, NACK packets) and packet overhead (SYNC, PID, bit stuffing, CRC, EOP). Adding in those factors is left as an exercise for a later patch. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
