SMBus access functions assume that 16-bit values are formatted as
little endian numbers. The direct i2c access functions in regmap,
however, assume that 16-bit values are formatted as big endian numbers.
As a result, the current code returns different values if an i2c chip's
16-bit registers are accessed through i2c access functions vs. SMBus
access functions.
Use regmap_smbus_read_word_swapped and regmap_smbus_write_word_swapped
for 16-bit SMBus accesses if a chip is configured as REGMAP_ENDIAN_BIG.
If the chip is configured as REGMAP_ENDIAN_LITTLE, keep using
regmap_smbus_write_word_data and regmap_smbus_read_word_data. Otherwise
reject registration if the controller does not support direct i2c accesses.

a total of 217 non-merge commits with pretty much everything
being touched.
The most important bits are a ton of new documentation for
almost all usb gadget functions, a new isp1760 UDC driver,
several improvements to the old net2280 UDC driver, and
some minor tracepoint improvements to dwc3.
Other than that, a big list of minor cleanups, smaller bugfixes
and new features all over the place.

Pull ARM fixes from Russell King:
"A number of ARM fixes, the biggest is fixing a regression caused by
appended DT blobs exceeding 64K, causing the decompressor fixup code
to fail to patch the DT blob. Another important fix is for the ASID
allocator from Will Deacon which prevents some rare crashes seen on
some systems. Lastly, there's a build fix for v7M systems when printk
support is disabled.
The last two remaining fixes are more cosmetic - the IOMMU one
prevents an annoying harmless warning message, and we disable the
kernel strict memory permissions on non-MMU which can't support it
anyway"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8299/1: mm: ensure local active ASID is marked as allocated on rollover
ARM: 8298/1: ARM_KERNMEM_PERMS only works with MMU enabled
ARM: 8295/1: fix v7M build for !CONFIG_PRINTK
ARM: 8294/1: ATAG_DTB_COMPAT: remove the DT workspace's hardcoded 64KB size
ARM: 8288/1: dma-mapping: don't detach devices without an IOMMU during teardown
The FPU and DSP are enabled via the CP0 Status CU1 and MX bits by
kvm_mips_set_c0_status() on a guest exit, presumably in case there is
active state that needs saving if pre-emption occurs. However neither of
these bits are cleared again when returning to the guest.
This effectively gives the guest access to the FPU/DSP hardware after
the first guest exit even though it is not aware of its presence,
allowing FP instructions in guest user code to intermittently actually
execute instead of trapping into the guest OS for emulation. It will
then read & manipulate the hardware FP registers which technically
belong to the user process (e.g. QEMU), or are stale from another user
process. It can also crash the guest OS by causing an FP exception, for
which a guest exception handler won't have been registered.
First lets save and disable the FPU (and MSA) state with lose_fpu(1)
before entering the guest. This simplifies the problem, especially for
when guest FPU/MSA support is added in the future, and prevents FR=1 FPU
state being live when the FR bit gets cleared for the guest, which
according to the architecture causes the contents of the FPU and vector
registers to become UNPREDICTABLE.
We can then safely remove the enabling of the FPU in
kvm_mips_set_c0_status(), since there should never be any active FPU or
MSA state to save at pre-emption, which should plug the FPU leak.
DSP state is always live rather than being lazily restored, so for that
it is simpler to just clear the MX bit again when re-entering the guest.

Adding finish_resume_work into runtime resume callback fixes the issue.

According to the DWC2 datasheet, the HWCFG1 register stores
the configured endpoint directions for endpoints 0-15 in bit positions
0-31.
==========================
Endpoint Direction (EpDir)
This 32-bit field uses two bits per endpoint to determine the endpoint
direction.
Endpoint
Bits [31:30]: Endpoint 15 direction
Bits [29:28]: Endpoint 14 direction
....
Bits [3:2]: Endpoint 1 direction
Bits[1:0]: Endpoint 0 direction (always BIDIR)
==========================
The DWC2 driver is currently interpreting the contents of the register
as directions for endpoints 1-15 which leads to an error in determining
the configured endpoint directions in the core because the first 2 bits
determine the direction of endpoint 0 and not 1.
This is based on testing/next branch in Felipe's git.

It took me a few tries to figure out what this code did; lets rewrite
it into a more regular form.
The thing that makes this one 'special' is the BSG_F_BLOCK flag, if
that is not set we're not supposed/allowed to block and should spin
wait for completion.
The (new) io_wait_event() will never see a false condition in case of
the spinning and we will therefore not block.
