* usb: phy: twl4030-usb: don't enable PHY during initGrazvydas Ignotas2013-03-211-11/+9
| | | | | | | | | | There is no need to do it, otg.set_suspend(false) (which itself comes from runtime_pm OMAP glue calls) will enable it later anyway. This used to be the place where things were enabled if booted with cable connected before runtime_pm conversion, but now can be dropped.

* arm: tegra: fix Kconfig select clausesFelipe Balbi2013-03-202-4/+5
| | | | | | | | | | | | | | | | USB_ULPI and USB_ULPI_VIEWPORT shouldn't really be selected directly by anyone, but since Tegra still needs some time before turning ulpi viewport into a proper PHY driver, we need to keep the selects in place. This patch just fixes the conditional select so that it will continue to build after merging the latest PHY layer changes.

* usb: phy: ab8500-usb: update irq handling codeFabio Baltieri2013-03-183-96/+382
| | | | | | | | | | | | | | Update irq handling code to notify all possible link status changes of AB8500 and AB8505 to the ux500-musb glue driver. The additional event codes will be used for pm-runtime implementation, and are defined in a separate ux500-specific header. This also modify the irq registration code to use devm_* helpers and drop all non necessary fail path code.

* usb: gadget: uvc: Make video streaming buffer size comply with USB3.0 SSBhupesh Sharma2013-03-181-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per the USB3.0 specs, the bandwidth requirements of a UVC's video streaming endpoint will change to support super-speed. These changes will be dependent on whether the UVC video streaming endpoint is Bulk or Isochronous: - If video streaming endpoint is Isochronous: As per Section 4.4.8.2 (Isochronous Transfer Bandwidth Requirements) of the USB3.0 specs: A SuperSpeed isochronous endpoint can move up to three burst transactions of up to 16 maximum sized packets (3 * 16 * 1024 bytes) per service interval. - If video streaming endpoint is Bulk: As per 4.4.6.1 (Bulk Transfer Data Packet Size) of the USB3.0 specs: An endpoint for bulk transfers shall set the maximum data packet payload size in its endpoint descriptor to 1024 bytes. It also specifies the burst size that the endpoint can accept from or transmit on the SuperSpeed bus. The allowable burst size for a bulk endpoint shall be in the range of 1 to 16. So, in the Isochronous case, we can define the USB request's buffer to be equal to = (Maximum packet size) * (bMaxBurst + 1) * (Mult + 1), so that the UDC driver can try to send out this buffer in one Isochronous service interval. The same computation will hold good for the Bulk case as the Mult value is 0 here and we can have a USB request buffer of maximum 16 * 1024 bytes size, which can be sent out by the UDC driver as per the Bulk bandwidth allocation on the USB3 bus. This patch adds the above-mentioned support and is also USB2.0 backward compliant.

* usb: gadget: uvc: Delay the status stage when setting alternate setting 1Bhupesh Sharma2013-03-183-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the support in UVC webcam gadget design for providing USB_GADGET_DELAYED_STATUS in response to a set_interface(alt setting 1) command issue by the Host. The current UVC webcam gadget design generates a STREAMON event corresponding to a set_interface(alt setting 1) command from the Host. This STREAMON event will eventually be routed to a real V4L2 device. To start video streaming, it may be required to perform some register writes to a camera sensor device over slow external busses like I2C or SPI. So, it makes sense to ensure that we delay the STATUS stage of the set_interface (alt setting 1) command. Otherwise, a lot of ISOC IN tokens sent by the Host will be replied to by zero-length packets by the webcam device. On certain Hosts this may even lead to ISOC URBs been cancelled from the Host side. So, as soon as we finish doing all the "streaming" related stuff on the real V4L2 device, we call a STREAMON ioctl on the UVC side and from here we call the 'usb_composite_setup_continue' function to complete the status stage of the set_interface(alt setting 1) command. Further, we need to ensure that we queue no video buffers on the UVC webcam gadget, until we de-queue a video buffer from the V4L2 device. So, the application should call the STREAMON on UVC side only when it has dequeued sufficient buffers from the V4L2 side and queued them to the UVC gadget.
