2016-06-17usb: ehci: only shutdown opened controllerPeng Fan
If the usb controller is not running, no need to shutdown it, otherwise `usb stop` complains about: "EHCI failed to shut down host controller". To i.MX7D SDB, there are two usb ports, one Host, one OTG. If we only plug one udisk to the Host port and then `usb start`, the OTG controller for OTG port does not run actually. Then, if `usb stop`, the OTG controller for OTG port will also be shutdown, but it is not running. This patch adds a check to only shutdown the running controller.

2016-06-03usb: move CONFIG_USB_XHCI to Kconfig with renamingMasahiro Yamada
Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it into CONFIG_USB_XHCI_HCD. As commented in the help of "config USB_XHCI" entry, this has been a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI have been unified in favor of the former. Note: Some boards define CONFIG_USB_XHCI in their headers without CONFIG_USB, which does not meet the "depends on" in Kconfig. I added CONFIG_USB=y for those boards when converting. Otherwise, they would fail to build. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-05-06usb: dwc2: Add delay to fix the USB detection problem on SoCFPGAStefan Roese
With patch c998da0d (usb: Change power-on / scanning timeout handling), the USB scanning is started earlier and with a smaller timeout. This resulted on SoCFPGA (using the DWC2 driver) in some USB sticks not getting detected any more. This patch now adds a 1 second delay (in the host mode only) to the DWC2 driver before the scanning is started. With this delay, now all problematic USB keys are detected successfully again. And there is no need any more to change the delay / timeout in the common USB code (usb_hub.c).

2016-04-12sunxi: H3: Do not clear usb companion clk-gate / reset on removeHans de Goede
On the H3 we need to enable the clk and de-assert the reset of the companion to be able to talk to the actual usb host controller. Before this commit we were also disabling the companion clk-gate / asserting its reset on remove, causing the later remove callback of the companion itself to (sometimes) fail with: ERROR: USB HC reset timed out!

2016-04-01usb: ulpi: Fix compile warning in read/write on 64-bit machines.Mateusz Kulikowski
ulpi_read and ulpi_write are used to read/write registers via ULPI bus. Code generates compilation warnings on 64-bit machines where pointer is cast to u32. This patch drops all but last 8 bits of register address. It is possible, because addresses on ULPI bus are 6- or 8-bit. It is not possible (according to ULPI 1.1 spec) to have more than 8-bit addressing. This patch should not cause regressions as all calls to ulpi_read/write use either structure pointer (@ address 0) or integer offsets cast to pointer - addresses requested are way below 8-bit range.
