Roger Quadros 67c8d06364 ARM: OMAP2+: omap-usb-host: Get rid of platform_data from struct usbhs_phy_data
The platform data bits can be inferred from the other members of
struct usbhs_phy_data. So get rid of the platform_data member.

Build the platform data for the PHY device in usbhs_init_phys() instead.

Roger Quadros bd27fa44e1 usb: phy: generic: Don't use regulator framework for RESET line
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.

checkpatch.pl has some valid complaints about style in s3c-hsotg.c:
- macro with 'if' should be really enclosed in 'do {} while (0)'

Andrzej Pietrasiewicz 8b903fd7f9 usb: gadget: f_mass_storage: add a level of indirection for luns storage
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.

Andrzej Pietrasiewicz 6fdc5dd25e usb: gadget: create a utility module for mass_storage
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.

Sergei Shtylyov ea78201e2e usb: musb: davinci: fix resources passed to MUSB driver for DM6467
After commit 09fc7d22b0 (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().

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.

Linus Torvalds 434ac47d0f Driver core / sysfs fixes for 3.12-rc3
Here are 2 fixes for 3.12-rc3.  One fixes a sysfs problem with mounting caused
 by 3.12-rc1, and the other is a bug reported by the chromeos developers with
 the driver core.
 
 Both have been in linux-next for a bit.

Ingo Molnar 14951f22f1 Revert "perf symbols: Demangle cloned functions"
This reverts commit de95ab5364.

Markus Trippelsdorf reported that this commit broke 'perf top':

 > I just see a gray screen with no text at all. Sometimes the
 > following error messages are printed:
 >
 >  *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0
 >  ***
 >  *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 ***

While this code is fixable, the commit itself fails on several levels:

 - it should have been a separate helper function
 - why the heck does it do strchr() twice
 - it casts a const char * over into char *
 - sloppy style
 - it's not even a regression fix!

So lets revert it and re-try the patch in v3.13.

     cpufreq_get() is called before registering a cpufreq driver.

  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().

Yinghai Lu f41f064cf4 PCI: Workaround missing pci_set_master in pci drivers
Ben Herrenschmidt found that commit 928bea9648 ("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.
