2013-06-30dfu:function: Fix number of allocated DFU function pointersLukasz Majewski
This subtle change fix problem with too small amount of allocated memory to store DFU function pointers. One needs to allocate extra space for sentinel NULL pointer in this array of function pointers. With the previous code, the NULL value overwrites malloc internal data and afterwards free(f_dfu->function) crashes.

2013-06-30usb, dfu gadget: switch to dfu mode in dfu_bindHeiko Schocher
- set in to_dfu_mode() f_dfu->dfu_state = DFU_STATE_dfuIDLE as after every to_dfu_mode call this is done, so move this into to_dfu_mode - switch in dfu_bind() into dfu mode: This fixes wrong "dfu-util -l" output, when calling "dfu-util -l" after a board reset, without doing a download before.

2013-05-05pxa27x_udc: remove call to unimplemented set_GPIO_mode()Mike Dunn
If CONFIG_USB_DEV_PULLUP_GPIO is defined, a link error occurs because the set_GPIO_mode() helper function is not implemented. This function doesn't do much except make the code a little more readable, so I just manually coded its equivalent and removed the prototype from the header file. It is invoked no where else in the code. While I was at it, I noticed that two other function prototypes in the same header file are also neither implemented nor invoked anywhere, so I removed them as well.

2013-03-18usb:composite:fix Provide function data when addressing device with only one ↵Lukasz Majewski
interface This commit fixes problems with some non-standard requests send with device address instead of interface address (bmRequestType.Receipent field). This happens with dfu-util (debian version: 0.5), which address non standard requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device. Without this fix, the above request is STALLED, and hence causes dfu-util to assume some standard configuration (packet size = 1024B instead of 4096B) In turn it displays following errors: Error obtaining DFU functional descriptor Warning: Assuming DFU version 1.0 Warning: Transfer size can not be detected ... Warning: Trying default transfer size 1024 This fix allows passing non-standard request to function setup code, where it shall be handled.

2012-11-20musb-new: port of Linux musb driverIlya Yanok
Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>

2012-11-04usb gadget ether: Fix warning in is_eth_addr_valid()Tom Rini
The gadget ethernet driver needs to keep copies of the MAC address (at both endpoints) as strings so it needs a custom function for validation of the MAC. It was not however performing a totally correct check and also was emitting a warning about a set but unused variable. The solution to both is that after checking the string contents we use the standard test for a valid MAC.

This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support.

2011-12-16USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini
In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase where the previous behavior of leaving wMaxPacketSize be unaligned caused fatal problems. The initial fix for this problem was incomplete however as it showed another cases of non-aligned access that previously worked implicitly. This switches to making sure that all access of wMaxPacketSize are done via (get|put)_unaligned. In order to maintain a level of readability to the code in some cases we now use a variable for the value of wMaxPacketSize and in others, a macro.
