2013-10-04usb: phy: Pass OTG FSM pointer to callback functionsAnton Tikhomirov3-31/+31
struct otg_fsm may be embedded to device's context structure. The callbacks may require pointer to struct otg_fsm to obtain necessary data for its operation (example: regulator reference for drv_vbus()).

2013-10-04usb: gadget: udc-core: Do not report -EISNAM error from gadgetfsFabio Estevam1-1/+2
When mounting a gadgetfs the following error message is seen: $ modprobe gadgetfs gadgetfs: USB Gadget filesystem, version 24 Aug 2004 $ mkdir /dev/gadget $ mount -t gadgetfs none /dev/gadget nop ci_hdrc.0: failed to start (null): -120 The error comes from gadgetfs_probe(), which returns -EISNAM (-120). As Alan Stern explains[1], this is the normal behavior: "It is a temporary measure, used only when the file system is set up initially. The real bind routine is gadgetfs_bind(), which gets called when userspace configures the gadget. In short, this is how it is intended to work. It isn't a bug." [1] http://marc.info/?l=linux-usb&m=138029668707075&w=2 So in order to prevent the error message, do not report EISNAM as an error.

2013-10-04usb: phy: generic: Don't use regulator framework for RESET lineRoger Quadros3-32/+60
Modelling the RESET line as a regulator supply wasn't a good idea as it kind of abuses the regulator framework and also makes adaptation code more complex. Instead, manage the RESET gpio line directly in the driver. Update the device tree binding information. This also makes us easy to migrate to a dedicated GPIO RESET controller whenever it becomes available. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-10-01usb: gadget: f_mass_storage: add a level of indirection for luns storageAndrzej Pietrasiewicz1-19/+41
This is needed to prepare for configfs integration. So far the luns have been allocated during gadget's initialization, based on the nluns module parameter's value; the exact number is known when the gadget is initialized and that number of luns is allocated in one go; they all will be used. When configfs is in place, the luns will be created one-by-one by the user. Once the user is satisfied with the number of luns, they activate the gadget. The number of luns must be <= FSG_MAX_LUN (currently 8), but other than that it is not known up front and the user need not use contiguous numbering (apart from the default lun #0). On the other hand, the function code uses lun numbers to identify them and the number needs to be used as an index into an array. Given the above, an array needs to be allocated, but it might happen that 7 out of its 8 elements will not be used. On my machine sizeof(struct fsg_lun) == 462, so > 3k of memory is allocated but not used in the worst case. By adding another level of indirection (allocating an array of pointers to struct fsg_lun and then allocating individual luns instead of an array of struct fsg_luns) at most 7 pointers are wasted, which is much less. This patch also changes some for/while loops to cope with the fact that in the luns array some entries are potentially empty.

2013-10-01usb: gadget: f_mass_storage: factor out a header fileAndrzej Pietrasiewicz2-110/+133

2013-10-01usb: gadget: create a utility module for mass_storageAndrzej Pietrasiewicz8-291/+423
Converting to configfs requires making the f_mass_storage.c a module. But first we need to get rid of "#include "storage_common.c". This patch makes storage_common.c a separately compiled file, which is built as a utility module named u_ms.ko. After all mass storage users are converted to the new function interface this module can be eliminated by merging it with the mass storage function's module. USB descriptors are exported so that they can be accessed from f_mass_storage. FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user. Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c. The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so instead of using a global variable the f_mass_storage introduces fsg_num_buffers member in fsg_common (and fsg_config). fsg_strings and fsg_stringtab are moved to f_mass_storage.c.

2013-10-01usb: musb: davinci: fix resources passed to MUSB driver for DM6467Sergei Shtylyov1-1/+10
After commit 09fc7d22b024692b2fe8a943b246de1af307132b (usb: musb: fix incorrect usage of resource pointer), CPPI DMA driver on DaVinci DM6467 can't detect its dedicated IRQ and so the MUSB IRQ is erroneously used instead. This is because only 2 resources are passed to the MUSB driver from the DaVinci glue layer, so fix this by always copying 3 resources (it's safe since a placeholder for the 3rd resource is always there) and passing 'pdev->num_resources' instead of the size of musb_resources[] to platform_device_add_resources().

2013-10-01usb: dwc3: Remove additional delay of 100ms when resumingVivek Gautam1-1/+0
This delay got introduced in: "7415f17 usb: dwc3: core: add power management support" which reflected similar code in dwc3_core_soft_reset() function. However, originally the delay of 100ms in dwc3_core_soft_reset() was meant to assist USB2PHY and USB3PHY reset, not for usb_phy_init() sequence. We should get rid of this delay, since things will still work fine without this.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These fix one recent cpufreq regression, a few older bugs that may harm users and a kerneldoc typo. Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler()
2013-09-28PCI: Workaround missing pci_set_master in pci driversYinghai Lu1-1/+7
Ben Herrenschmidt found that commit 928bea964827 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

2013-09-28drm/msm: deal with mach/iommu.h removalRob Clark1-2/+2
We still need an API exported by msm iommu driver (but not visible in any public header anymore). For now, just declare the prototype ourselves, but when msm iommu driver provides a better option, use that instead. Signed-off-by: Rob Clark <robdclark@gmail.com>
