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).

There could be runtime determined board specific reason why a EHCI initialization fails (e.g. ENODEV if a Port is not available). In this case, properly return the error code.

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.

2016-03-17dm: usb: Unbind old block devices when shutting down USBSimon Glass
When 'usb start' is used, block devices are created for any USB flash sticks and disks, etc. When 'usb stop' is used, these block devices are currently not removed. We don't want old block devices hanging around since they can still be visible to U-Boot. Therefore, when USB is shut down, remove and unbind all the block devices created by the USB subsystem. Possibly we should unbind all devices which don't cause problems by being unbound. Most likely we can remove everything except USB controllers, hubs and emulators. We can consider that later.
