* Merge tag 'usb-for-v3.20' of ↵Greg Kroah-Hartman2015-02-04102-2238/+8135

It's a total of 217 non-merge commits with pretty much everything being touched. The most important bits are a ton of new documentation for almost all usb gadget functions, a new isp1760 UDC driver, several improvements to the old net2280 UDC driver, and some minor tracepoint improvements to dwc3. Other than that, a big list of minor cleanups, smaller bugfixes and new features all over the place. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: musb: fix device hotplug behind hubBin Liu2015-02-042-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 889ad3b "usb: musb: try a race-free wakeup" breaks device hotplug enumeraitonn when the device is connected behind a hub while usb autosuspend is enabled. Adding finish_resume_work into runtime resume callback fixes the issue. Also resume root hub is required to resume the bus from runtime suspend, so move musb_host_resume_root_hub() back to its original location, where handles RESUME interrupt.

| * usb: dwc2: Fix a bug in reading the endpoint directions from reg.Roshan Pius2015-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the DWC2 datasheet, the HWCFG1 register stores the configured endpoint directions for endpoints 0-15 in bit positions 0-31. ========================== Endpoint Direction (EpDir) This 32-bit field uses two bits per endpoint to determine the endpoint direction. Endpoint Bits [31:30]: Endpoint 15 direction Bits [29:28]: Endpoint 14 direction .... Bits [3:2]: Endpoint 1 direction Bits[1:0]: Endpoint 0 direction (always BIDIR) ========================== The DWC2 driver is currently interpreting the contents of the register as directions for endpoints 1-15 which leads to an error in determining the configured endpoint directions in the core because the first 2 bits determine the direction of endpoint 0 and not 1. This is based on testing/next branch in Felipe's git. Signed-off-by: Roshan Pius <rpius@chromium.org> Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

The USB PHY reset gpio is defined in the dts file as: reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>; , which means it is active low, so what the gpio reset pin needs to do in this case is the following: - Go to logic level 0 to reset the USB PHY - Stay at 0 for a bit - Go back to logic level 1 When switching to gpiod API we need to following according to Documentation/gpio/consumer.txt: "The first thing a driver must do with a GPIO is setting its direction. If no direction-setting flags have been given to gpiod_get*(), this is done by invoking one of the gpiod_direction_*() functions: int gpiod_direction_input(struct gpio_desc *desc) int gpiod_direction_output(struct gpio_desc *desc, int value)" Since no direction-setting flags have been given to devm_gpiod_get_optional() in our case, we need to use gpiod_direction_output to comply with the gpiod API. With this change the USB PHY reset performs a proper reset, the kernel boots fine and USB host is functional.

| * usb: renesas_usbhs: fix NULL pointer dereference in dma_release_channel()Yoshihiro Shimoda2015-01-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue that the following commit causes NULL pointer dereference in dma_release_channel(). "usb: renesas_usbhs: add support for requesting DT DMA" (commit id abd2dbf6bb1b5f3a03a8c76b1a8879da1dd30caa) The usbhsf_dma_init_dt() should set fifo->{t,r}x_chan to NULL if dma_request_slave_channel_reason() returns IS_ERR value. Otherwise, usbhsf_dma_quit() will call dma_release_channel(), and then NULL pointer dereference happens.
