Pull USB fixes from Greg KH:
"Here are a bunch of USB fixes for 3.13-rc3.
Nothing major, but we seem to have an argument about a XHCI fix, so
I'm not including a revert that Sarah requested, because that breaks a
USB network driver, and I can't revert the USB network driver fix
without reintroducing other bugs that it fixed. So as it is,
everything should now be working. Worse case, I can revert the XHCI
fix before 3.13-final is out, but it seems to work well here with my
testing, so all should be good.
Other than that, some driver updates based on reports"

This adds external USB phy support to USB HCD driver that
allows to find and initialize external USB phy, bound to
the HCD, when the HCD is added.
The usb_add_hcd function returns -EPROBE_DEFER if the USB
phy, bound to the HCD, is not ready.
If no USB phy is bound, the HCD is initialized as usual.

This adds remove_phy flag to the HCD structure. If the flag is
set and if hcd->phy is valid, the phy is shutdown and released
whenever usb_add_hcd fails or usb_hcd_remove is called.
This can be used by the HCD drivers to auto-remove
the external USB phy when it is no longer needed.

027a485d12e0 ("sysfs: use a separate locking class for open files
depending on mmap") assigned different lockdep key to
sysfs_open_file->mutex depending on whether the file implements mmap
or not in an attempt to avoid spurious lockdep warning caused by
merging of regular and bin file paths.
While this restored some of the original behavior of using different
locks (at least lockdep is concerned) for the different clases of
files. The restoration wasn't full because now the lockdep key
assignment depends on whether the file has mmap or not instead of
whether it's a regular file or not.
This means that bin files which don't implement mmap will get assigned
the same lockdep class as regular files. This is problematic because
file_operations for bin files still implements the mmap file operation
and checking whether the sysfs file actually implements mmap happens
in the file operation after grabbing @sysfs_open_file->mutex. We
still end up adding locking dependency from mmap locking to
sysfs_open_file->mutex to the regular file mutex which triggers
spurious circular locking warning.
Fix it by restoring the original behavior fully by differentiating
lockdep key by whether the file is regular or bin, instead of the
existence of mmap.

Add a flag to tell the PCI subsystem that kernel is shutting down in
preparation to kexec a kernel. Add code in PCI subsystem to use this flag
to clear Bus Master bit on PCI devices only in case of kexec reboot.
This fixes a power-off problem on Acer Aspire V5-573G and likely other
machines and avoids any other issues caused by clearing Bus Master bit on
PCI devices in normal shutdown path. The problem was introduced by
b566a22c2332 ("PCI: disable Bus Master on PCI device shutdown").
This patch is based on discussion at

Commit 7ce93f3 (ARM: OMAP2+: Fix more missing data for omap3.dtsi file)
fixed missing device tree data for omaps, but did not account for some of the
hardware modules being inaccessible for secure omaps. This causes the
following error on secure omaps:

Let's fix the issue by adding omap34xx-hs.dtsi and omap36xx-hs.dtsi and make
n900, n9 and n950 to use them. This way we have the aes, sham and timer12
disabled for secure devices the same way legacy booting does based on the
omap34xx_gp_hwmod_ocp_ifs and omap36xx_gp_hwmod_ocp_ifs arrays in
omap_hwmod_3xxx_data.c.

There is an as-yet unexplained bug that sometimes prevents (or delays)
the driver seeing the completion event for a completed MCDI request on
the SFC9120. The requested configuration change will have happened
but the driver assumes it to have failed, and this can result in
further failures. We can mitigate this by polling for completion
after unsuccessfully waiting for an event.

rx_prefix_size is 4-bytes aligned on Falcon/Siena (16 bytes), but it is equal
to 14 on EF10. So, it should be taken into account if arch requires IP header
to be 4-bytes aligned (via NET_IP_ALIGN).

There is a single MCDI PTP operation for setting the frequency
adjustment and applying a time offset to the hardware clock. When
applying a time offset we should not change the frequency adjustment.
These two operations can now be requested separately but this requires
a flash firmware update. Keep using the single operation, but
remember and repeat the previous frequency adjustment.

This disables PTP when we bring the interface down to avoid getting
unmatched RX timestamp events, and tries to re-enable it when bringing
the interface up.
[bwh: Make efx_ptp_stop() safe on Falcon. Introduce
efx_ptp_{start,stop}_datapath() functions; we'll expand them later.]

In case of a flood of PTP packets, the timestamp peripheral and MC
firmware on the SFN[56]322F boards may not be able to provide
timestamp events for all packets. Don't complain too much about this.

The am3517 is wrongly booting as omap3 which means that the am3517
specific devices like Ethernet won't work when booted with device
tree. Now with the new devices defined in am3517.dtsi, let's use
that instead of the omap3.dtsi, and add a separate machine entry
for am3517 so am3517-evm can use it.

we currently have not defined. Let's fix that by adding am3517.dtsi

We have some device tree properties where the ti,hwmod have multiple
values:
am33xx.dtsi: ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi: ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi: ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi: ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi: ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi: ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi: ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.
So they should all be fixed up to be separate devices in the .dts files.
We also have the related data removed for at least omap4 in commit
3b9b10151c68 (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.
So we need to fix two bugs:
1. We are only checking the first entry of the ti,hwmods property
This means that we're only initializing the first hwmods entry
instead of the ones listed in the ti,hwmods property.
2. We are only checking the child nodes, not the nodes themselves
This means that anything listed at OCP level is currently just
ignored and unitialized and at least the omap4 case, with the
legacy data missing from the hwmod.
Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.
While at it, let's also add some warnings for the bad data so it's
easier to fix.
