* usb: usbtest: two super speed fixes for usbtestPaul Zimmerman2012-05-01
| | | | | | | | | | | | | bMaxPacketSize0 field for super speed is a power of 2, not a count. The size itself is always 512. Max packet size for a super speed bulk endpoint is 1024, so allocate the urb size in halt_simple() accordingly.

* USB: Add driver for NXP ISP1301 USB transceiverRoland Stigge2012-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | This new driver registers the NXP ISP1301 chip via the I2C subsystem. The chip is the USB transceiver shared by ohci-nxp, lpc32xx_udc (gadget) and isp1301_omap. ISP1301 is a very low-level driver that primarily separates out the I2C client registration of the ISP1301 chip (including instantiation via DT), used by other drivers, and declares the chip's registers. It's only a helper driver for some OHCI and USB device drivers. The driver can be considered as a register set extension of ohci-nxp, lpc32xx-udc and isp1301_omap, which in turn know best what to do with the low level functionality (individual ISP1301 registers and timing, see the different initialization strategies in those drivers). Those drivers previously internally duplicated ISP1301 register definitions which is solved by this new isp1301 driver. The ISP1301 registers exposed via isp1301.h can be accessed by other drivers using it with standard i2c_smbus_*() accesses. Following patches let the respective USB host and gadget drivers use this driver, instead of duplicating ISP1301 handling.

* usbhid: prevent deadlock during timeoutOliver Neukum2012-05-01
| | | | | | | | | | | | | | | On some HCDs usb_unlink_urb() can directly call the completion handler. That limits the spinlocks that can be taken in the handler to locks not held while calling usb_unlink_urb() To prevent a race with resubmission, this patch exposes usbcore's infrastructure for blocking submission, uses it and so drops the lock without causing a race in usbhid.

* USB: ehci-tegra: remove PORT_RWC_BITS when setting USB_PORT_FEAT_ENABLEStephen Warren2012-04-25
| | | | | | | | | | | | | | | In the SetPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control() would read from status_reg, modify the value, and write the result back to status_reg. This would clear any bits in PORT_RWC_BITS that were set in the register. Fix this by masking these bits off before the write. This is logically the same change as 6d5f89c "USB: EHCI: remove PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE", but applied to the Tegra driver rather than the USB core.

* USB: serial: fix interface data useJohan Hovold2012-04-25
| | | | | | | | | | | | | | The interface data should not be used as a flag to signal disconnect. Now that all serial drivers use the usb_serial disconnect flag and mutex, we can set the interface data prior to registering the ports and there's no need to clear it at disconnect. This should hopefully also make it more clear that the interface data is not a flag, which could prevent future misuse.

* EHCI: maintain the ehci->command value properlyAlan Stern2012-04-23
| | | | | | | | | | | | | | The ehci-hcd driver is a little haphazard about keeping track of the state of the USBCMD register. The ehci->command field is supposed to hold the register's value (apart from a few special bits) at all times, but it isn't maintained properly. This patch (as1543) cleans up the situation. It keeps ehci->command up-to-date, and uses that value rather than reading the register from the hardware whenever possible.
