2013-10-20usb: gadget: ether set wMaxPacketSizeTroy Kisky
set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

2013-10-20exynos: usb: Switch USB VBUS GPIOs to be device tree configuredJulius Werner
Some Exynos boards, such as the SMDK5250, control USB port power through a GPIO pin. For now this had been hardcoded in the exynos5-dt board file, but not all boards use the same pin, requiring local changes to support different boards. This patch moves the GPIO initialization into the USB host controller drivers which they belong to, and uses the samsung,vbus-gpio parameter in the device tree to configure it.

2013-10-17exynos: i2c: Change FDT bus setup code to enumerate ports correctlySimon Glass
At present the i2c ports are enumerated in a strange way - the fdtdec_find_aliases_for_id() function is used, but then the ID returned is ignored and the ports are renumbered. The effect is the same provided that the device tree has the ports in the same order, or uses aliases, and has no gaps, but it is not correct. Adjust the code to use the function as intended. This will allows device tree aliases to change the device order if required. As a result, the i2c_busses variable is dropped. We can't be sure that there are no 'holes' in the list of buses, so must check the whole array. Note: it seems that non-FDT operation is now broken in this drive and will need to be reinstated for upstream.

Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1.
