83280e90ef USB fixes for 4.10-rc3
Here are a bunch of USB fixes for 4.10-rc3.  Yeah, it's a lot, an
 artifact of the holiday break I think.  Lots of gadget and the usual
 XHCI fixups for reported issues (one day that driver will calm down...)
 Also included are a bunch of usb-serial driver fixes, and for good
 measure, a number of much-reported MUSB driver issues have finally been
 resolved.
 
 All of these have been in linux-next with no reported issues.

 "This has one fix to make i915 work when using Xen SWIOTLB, and a

  The feature from Geert is on top of v4.10 merge window commit
  (specifically you pulling my previous branch), as his changes were
  dependent on the Documentation/ movement patches.

  I figured it would just easier than me trying than to cherry-pick the
  Documentation patches to satisfy git.

  The patches have been soaking since 12/20, albeit I updated the last
  patch due to linux-next catching an compiler error and adding an
  Tested-and-Reported-by tag"

Pull power management fixes from Rafael Wysocki:
 "These fix a few issues in the intel_pstate driver, a documetation
  issue, a false-positive compiler warning in the generic power domains
  framework and two problems in the devfreq subsystem. They also update
  the MAINTAINERS entry for devfreq and add a new "compatible" string to
  the generic cpufreq-dt driver.

  Specifics:

   - Fix a few intel_pstate driver issues: add missing locking it two
     places, avoid exposing a useless debugfs interface and keep the
     attribute values in sysfs in sync (Rafael Wysocki).

   - Drop confusing kernel-doc references related to power management
     and ACPI from the driver API manual (Rafael Wysocki).

   - Make a false-positive compiler warning in the generic power domains
     framework go away (Augusto Mecking Caringi).

   - Fix two initialization issues in the devfreq subsystem and update
     the MAINTAINERS entry for it (Chanwoo Choi).

7453c549f5 swiotlb: Export swiotlb_max_segment to users
So they can figure out what is the optimal number of pages
that can be contingously stitched together without fear of
bounce buffer.

We also expose an mechanism for sub-users of SWIOTLB API, such
as Xen-SWIOTLB to set the max segment value. And lastly
if swiotlb=force is set (which mandates we bounce buffer everything)
we set max_segment so at least we can bounce buffer one 4K page
instead of a giant 512KB one for which we may not have space.

The gpiod_get* function family does not want the -gpio suffix.
Use devm_gpiod_get_index_optional instead of devm_gpiod_get_optional.
The descriptor based APIs handle active high/low automatically.
The vbus-gpios are output, request enable while getting the gpio.
Don't try to get any vbus-gpios for ports outside num-ports.

b400792732 This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
 regressions introduced during the merge window, and about half of
 the changes are for mach-omap2.
 
 A couple of patches are just cleanups and dead code removal that I would
 not normally have considered for merging after -rc2, but I decided to
 take them along with the fixes this time.
 
 Notable fixes include:
 
 - removing the skeleton.dtsi include broke a number of machines, and we
   have to put empty /chosen nodes back to be able to pass kernel command
   lines as before
 
 - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200,

c48400baa0 usb: musb: dsps: implement clear_ep_rxintr() callback
During dma teardown for dequque urb, if musb load is high, musb might
generate bogus rx ep interrupt even when the rx fifo is flushed. In such
case any of the follow log messages could happen.

    musb_host_rx 1853: BOGUS RX2 ready, csr 0000, count 0

    musb_host_rx 1936: RX3 dma busy, csr 2020

As mentioned in the current inline comment, clearing ep interrupt in the
teardown path avoids the bogus interrupt, so implement clear_ep_rxintr()
callback.

This bug seems to be existing since the initial driver for musb support,
but I only validated the fix back to v4.1, so only cc stable for v4.1+.

696c7f8e03 ACPI / DMAR: Avoid passing NULL to acpi_put_table()
Linus reported that commit 174cc7187e "ACPICA: Tables: Back port
acpi_get_table_with_size() and early_acpi_os_unmap_memory() from
Linux kernel" added a new warning on his desktop system:

 ACPI Warning: Table ffffffff9fe6c0a0, Validation count is zero before decrement

which turns out to come from the acpi_put_table() in
detect_intel_iommu().

This happens if the DMAR table is not present in which case NULL is
passed to acpi_put_table() which doesn't check against that and
attempts to handle it regardless.

For this reason, check the pointer passed to acpi_put_table()
before invoking it.

38e5a85562 net: systemport: Pad packet before inserting TSB
Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.

For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.

Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

14ba972842 nvmem: imx-ocotp: Fix wrong register size
All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is
an exception and has only 2kbit fuses.

In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is
described in chapter 46.1.1 with:
"32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)."

In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is
described in chapter 34.1.1 with:
"32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)."

Since the Freescale Linux kernel OCOTP driver works with a fuses size of
2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula
to calculate the correct fuses size has to be 256x8.
