2014-11-18clk: propagate parent change up one levelTomasz Stanislawski1-0/+6
This patch adds support for propagation of setup of clock's parent one level up. This feature is helpful when a driver changes topology of its clocks using clk_set_parent(). The problem occurs when on one platform/SoC driver's clock is located at MUX output but on the other platform/SoC there is a gated proxy clock between the MUX and driver's clock. In such a case, driver's code has to be modified to use one clock for enabling and the other clock for setup of a parent. The code updates are avoided by propagating setup of a parent up one level. Additionally, this patch adds CLK_SET_PARENT_PARENT (sorry for naming) flag to inform clk-core that clk_set_parent() should be propagated.

2014-11-18usb: gadget: f_fs: add aio supportRobert Baldyga1-26/+239
This patch adds asynchronous I/O support for FunctionFS endpoint files. It adds ffs_epfile_aio_write() and ffs_epfile_aio_read() functions responsible for preparing AIO operations. It also modifies ffs_epfile_io() function, adding aio handling code. Instead of extending list of parameters of this function, there is new struct ffs_io_data which contains all information needed to perform I/O operation. Pointer to this struct replaces "buf" and "len" parameters of ffs_epfile_io() function. Allocated buffer is freed immediately only after sync operation, because in async IO it's freed in complete funcion. For each async operation an USB request is allocated, because it allows to have more than one request queued on single endpoint. According to changes in ffs_epfile_io() function, functions ffs_epfile_write() and ffs_epfile_read() are updated to use new API. For asynchronous I/O operations there is new request complete function named ffs_epfile_async_io_complete(), which completes AIO operation, and frees used memory.

2014-11-18usb: gadget: f_fs: add poll for endpoint 0Robert Baldyga1-0/+42
This patch adds poll function for file representing ep0. Ability of read from or write to ep0 file is related with actual state of ffs: - When desctiptors or strings are not written yet, POLLOUT flag is set. - If there is any event to read, POLLIN flag is set. - If setup request was read, POLLIN and POLLOUT flag is set, to allow send response (by performing I/O operation consistent with setup request direction) or set stall (by performing I/O operation opposite setup request direction).

2014-11-18usb: gadget: f_fs: fix setup request handlingRobert Baldyga2-2/+1
This patch fixes __ffs_ep0_queue_wait() function, which now returns number of bytes transferred in USB request or error code in case of failure. This is needed by ffs_ep0_read() function, when read data is copied to userspace. It also cleans up code by removing usused variable ep0req_status.

2014-11-18usb: gadget: functionfs: replace FFS_SETUP_STATUS with an inline functionMichal Nazarewicz2-10/+19
The FFS_SETUP_STATUS macro could be trivialy replaced with an static inline function but more importantly its name was tad confusing. The name suggested it was a simple accessor macro but it actually did change the state of the ffs_data structure perfomring a FFS_SETUP_CANCELLED -> FFS_NO_SETUP transition. The name of the function -- ffs_setup_state_clear_cancelled -- should better describe what the function actually does.

Fix possible NULL pointer dereference introduced in 219580e64f035bb9018dbb08d340f90b0ac50f8c usb: f_fs: check quirk to pad epout buf size when not aligned to maxpacketsize In cases we do wait with: wait_event_interruptible(epfile->wait, (ep = epfile->ep)); for endpoint to be enabled, functionfs_bind() has not been called yet and epfile->ffs->gadget is still NULL and the automatic variable 'gadget' has been initialized with NULL at the point of its definition. Later on it is used as a parameter to: usb_ep_align_maybe(gadget, ep->ep, len) which in turn dereferences it.

2014-11-18usb: gadget: nokia: fix error recovery path for optional functionsAndrzej Pietrasiewicz1-3/+3
In the nokia gadget some USB functions (obex 1 and 2, phonet) are optional. If at the start of nokia_bind_config e.g. fi_phonet is an error pointer, which can happen because we don't fail the bind process if usb_get_function_instance() fails for fi_phonet, then f_phonet is NULL, and phonet_stat = usb_add_function(c, f_phonet); is never called and phonet_stat remains 0. If, in these circumstances, we hit the err_conf label then !phonet_stat evaluates to true and we try usb_remove_function() with its second parameter being f_phonet which is NULL and it causes NULL pointer dereference. This patch changes the initial values of (obex1|obex2|phonet)_stat to a nonzero value so that if the err_conf label is hit while the respective functions have not been acquired the usb_remove_function() is not called for those functions.
