* udc: dfu: s3c_udc: Provide function to check if USB reset was assertedLukasz Majewski2014-09-02-0/+5
| | | | | | | | | | | New dfu_usb_get_reset() method is necessary to distinct two different use cases of dfu-util program. This method checks if the USB bus reset has been really performed after DFU DETACH. Without this function the previous DFU behavior is preserved.

* usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driverLukasz Majewski2014-02-06-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The Samsung's UDC driver is not anymore copying data from USB requests to aligned internal buffers. Now it works directly in data allocated in the upper layers like UMS, DFU, THOR. This change is possible since those gadgets now must take care to allocate buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE). This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer aligned to cache line in both starting address and its size. Sometimes it is enough to just use memalign() with size being a multiplication of cache line size.

* lin_gadget: use common linux/compat.hMike Frysinger2012-04-30-2/+3
| | | | | | | | | | | | | | | | Merge our duplicate definitions with the common header. Also fix drivers/usb/gadget/s3c_udc_otg_xfer_dma.c to use min() instead of min_t() since we remove the latter from compat.h. Additionally use memalign() directly as the lin_gadget specific kmalloc() macro is removed from lin_gadget_compat.h by this patch.

* USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini2011-12-16-4/+6
| | | | | | | | | | | | | | | | | | | | | | 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.
