Some devices expose an ultra-low-power (ULP) mode entry mask for
each channel. If the mask is set, the device cannot enter ULP so
long as the corresponding channel remains in an active state.
The vendor has advised setting the mask for any disabled channel.
To accommodate this suggestion, initially set all masks and then
clear them only if specified in the device tree.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

If the device suffers a spurious reset during ATI, there is no point
in enduring any further retries. Instead, simply return successfully
from the polling loop.
In this case, the interrupt handler will intervene and recognize the
device has been reset. It then proceeds to initialize the device and
trigger ATI once more.
As part of this change, swap the order of status field evaluation to
match that of the interrupt handler, and correct a nearby off-by-one
error that causes an error message to suggest the final attempt will
be retried.

If the device suffers a spurious reset while reacting to a previous
spurious reset, the second reset interrupt is preempted because the
ACK_RESET bit is written last.
To solve this problem, write the ACK_RESET bit prior to writing any
other registers. This ensures that any registers written before the
second spurious reset will be rewritten.
Last but not least, the order in which the ACK_RESET bit is written
relative to the second filter beta register is important for select
variants of silicon. Enforce the correct order so as to not clobber
the system status register.

Select variants of silicon silently mirror part of the event mask
register to the system setup register (0xD0), and vice versa. For
the following sequence:
1. Read registers 0xD0 onward and store their contents.
2. Modify the contents, including event mask fields.
3. Write registers 0xD0 onward with the modified contents.
4. Write register 0xD0 on its own again later, using the contents
from step 1 to populate any reserved fields.
...the event mask register (e.g. address 0xDA) has been corrupted
by writing register 0xD0 with contents that were made stale after
step 3.
To solve this problem, read register 0xD0 once more between steps
3 and 4. When register 0xD0 is written during step 4, the portion
which is mirrored to the event mask register already matches what
was written in step 3.

The release cycle of any key mapped to a slider gesture relies upon
trailing interrupts generated by other unmasked sources, the timing
and presence of which are inconsistent.
To solve this problem, explicitly report a release cycle to emulate
a full keystroke. Also, unmask touch interrupts if the slider press
event is defined; this ensures the device reports a final interrupt
with coordinate = 0xFFFF once the finger is lifted.
As a result of how the logic has been refactored, the press/release
event can now be mapped to a GPIO. This is more convenient than the
previous solution, which required each channel within the slider to
specify the same GPIO.
As part of this change, use the device's resolution rather than its
number of interrupt status registers to more safely determine if it
is capable of reporting gestures.
Last but not least, make the code a bit simpler by eliminating some
unnecessarily complex conditional statements and a macro that could
be derived using information that is already available.

If a positive swipe/flick gesture is defined but the corresponding
negative gesture is not, the former is inadvertently disabled. Fix
this by gently refactoring the logic responsible for disabling all
gestures by default.
As part of this change, make the code a bit simpler by eliminating
a superfluous conditional check. If a slider event does not define
an enable control, the second term of the bitwise AND operation is
simply 0xFFFF.

Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.

Sync up with mainline to get updates to OMAP4 keypad driver and other
upstream goodies.
Instead of a virtual kernel address use a pointer of the associated
struct page as second parameter of gnttab_end_foreign_access().
Most users have that pointer available already and are creating the
virtual address from it, risking problems in case the memory is
located in highmem.
gnttab_end_foreign_access() itself won't need to get the struct page
from the address again.

The status of the keys connected to the KPDPWR_N and RESIN_N pins
is identified by reading corresponding bits in the interrupt real
time status register. If the status has changed by the time that
the interrupt is handled then a press event will be missed.
Maintain a last known status variable to find unbalanced release
events and simulate press events for each accordingly.

On certain PMICs, an unexpected assertion of KPDPWR_DEB (the
positive logic hardware debounced power key signal) may be seen
during the falling edge of KPDPWR_N (i.e. a power key press) when
it occurs close to the rising edge of SLEEP_CLK. This then
triggers a spurious KPDPWR interrupt.
Handle this issue by adding software debouncing support to ignore
key events that occur within the hardware debounce delay after the
most recent key release event.

The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

Select callers of iqs7222_parse_props() do not expect a child node
to be derived and returned via pointer. As such, these callers set
**child_node to NULL. However, this pointer is dereferenced in all
cases.
To solve this problem, dereference the pointer only for cases that
expect a child node in the first place. In these cases, the caller
provides a valid pointer.

If fwnode_property_count_u32() returns a negative error code then,
because of type promotion, the "count > ARRAY_SIZE(pins)" condition
will be true. The negative "count" is type promoted to a high unsigned
size_t value.
That means the "else if (count < 0)" condition will always be false and
we don't print that error message or propagate the error code from
fwnode_property_count_u32() as intended.
Fix this by re-ordering the checks so that we check for negative first.

The drivers/platform/surface/surface3_button.c code is alsmost a 1:1 copy
of the soc_button_array code.
The only big difference is that it binds to an i2c_client rather then to
a platform_device. The cause of this is the ACPI resources for the MSHW0028
device containing a bogus I2cSerialBusV2 resource which causes the kernel
to instantiate an i2c_client for it instead of a platform_device.
Add "MSHW0028" to the ignore_serial_bus_ids[] list in drivers/apci/scan.c,
so that a platform_device will be instantiated and add support for
the MSHW0028 HID to soc_button_array.
This fully replaces surface3_button, which will be removed in a separate
commit (since it binds to the now no longer created i2c_client it no
longer does anyyhing after this commit).
Note the MSHW0028 id is used by Microsoft to describe the tablet buttons on
both the Surface 3 and the Surface 3 Pro and the actual API/implementation
for the Surface 3 Pro is quite different. The changes in this commit should
not impact the separate surfacepro3_button driver:
1. Because of the bogus I2cSerialBusV2 resource problem that driver binds
to the acpi_device itself, so instantiating a platform_device instead of
an i2c_client does not matter.
2. The soc_button_array driver will not bind to the MSHW0028 device on
the Surface 3 Pro, because it has no GPIO resources.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.
