2013-11-15tree-wide: use reinit_completion instead of INIT_COMPLETIONWolfram Sang
Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

2013-11-14Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-10-31DMA-API: usb: use dma_set_coherent_mask()Russell King
The correct way for a driver to specify the coherent DMA mask is not to directly access the field in the struct device, but to use dma_set_coherent_mask(). Only arch and bus code should access this member directly. Convert all direct write accesses to using the correct API.

MUSB should now work out of the box on AM335x-based boards (beagle bone white and black) with DMA thanks to Sebastian's work. We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/ by selecting CONFIG_USB_GADGET_VERBOSE. s3c-hsotg got quite a few non-critical fixes but also learned a few new tricks (isochronous transfers, multi count support). The Marvel USB3 Controller driver got a memory leak fix. devm_usb_get_phy() learned not to return NULL, ever. Other than these patches, we have the usual set of cleanups ranging from removal of unnecessary *_set_drvdata() to using SIMPLE_DEV_PM_OPS. Signed-of-by: Felipe Balbi <balbi@ti.com>

2013-10-10usb: gadget: f_mass_storage: make sysfs interface optionalAndrzej Pietrasiewicz
When configfs is in place, the luns will not be represented in sysfs, so there will be no struct device associated with a lun. In order to maintain compatibility and allow configfs adoption sysfs is made optional in this patch. As a consequence some debug macros need to be adjusted. Two new fields are added to struct fsg_lun: name and name_pfx. The "name" is for storing a string which is presented to the user instead of the dev_name. The "name_pfx", if non-NULL, is prepended to the "name" at printing time. The name_pfx is for a future lun.0, which will be a default group in mass_storage.<name>. By design at USB function configfs group's creation time its name is not known (but instead set a bit later in drivers/usb/gadget/configfs.c:function_make) and it is this name that serves the purpose of the said name prefix. So instead of copying a yet-unknown string a pointer to it is stored in struct fsg_lun.

2013-10-05usb: g_ffs: fix compilation warningDavid Cohen
If USB_FUNCTIONFS is selected without USB_FUNCTIONFS_ETH and USB_FUNCTIONFS_RNIS, u_ether.h won't be included and then USB_ETHERNET_MODULE_PARAMAETERS macro won't be available causing the following warning compilation: drivers/usb/gadget/g_ffs.c:81:1: warning: data definition has no type or storage class [enabled by default] drivers/usb/gadget/g_ffs.c:81:1: warning: type defaults to ‘int’ in declaration of ‘USB_ETHERNET_MODULE_PARAMETERS’ [-Wimplicit-int] drivers/usb/gadget/g_ffs.c:81:1: warning: function declaration isn’t a prototype [-Wstrict-prototypes] This patch fixes the warning by making USB_ETHERNET_MODULE_PARAMETERS to be used iff u_ether.h is included, otherwise it is not needed.
