Convert to use vm_fault_t type as return type for fault handler.
kbuild reported warning during testing of
*mm-create-the-new-vm_fault_t-type.patch* available in below link -
https://patchwork.kernel.org/patch/10752741/
kernel/memremap.c:46:34: warning: incorrect type in return expression
(different base types)
kernel/memremap.c:46:34: expected restricted vm_fault_t
kernel/memremap.c:46:34: got int
This patch has fixed the warnings and also hmm_devmem_fault() is
converted to return vm_fault_t to avoid further warnings.

Introduce watchdog driver for a various range of Mellanox Ethernet and
Infiniband switch systems.
Watchdog driver for Mellanox watchdog devices, implemented in
programmable logic device.
Main and auxiliary watchdog devices can exist on the same system.
There are several actions that can be defined in the watchdog:
system reset, start fans on full speed and increase a counter.
The last 2 actions are performed without a system reset.
Actions without reset are provided for auxiliary watchdog devices,
which is optional.
Access to HW registers is performed through generic
regmap interface.
There are 2 types of HW watchdog implementations.
Type 1: actual HW timeout can be defined as power of 2 msec.
e.g. timeout 20 sec will be rounded up to 32768 msec.;
maximum timeout period is 32 sec (32768 msec.);
get time-left isn't supported
Type 2: actual HW timeout is defined in sec. and it's the same as
user-defined timeout;
maximum timeout is 255 sec;
get time-left is supported;
Watchdog driver is probed from the common mlx_platform driver.

This adds the support for qcom watchdog suspend and resume
when entering and exiting deep sleep states. Otherwise
having watchdog active after suspend would result in unwanted

Pull pin control updates from Linus Walleij:
"This is a calm cycle, not much happened this time around: not even
much incremental development. Some three new drivers, that is all.
No core changes.
New drivers:
- NXP (ex Freescale) i.MX 8QM driver.
- NXP (ex Freescale) i.MX 8MM driver.
- AT91 SAM9X60 subdriver.
Improvements:
- Support for external interrups (EINT) on Mediatek virtual GPIOs.
- Make BCM2835 pin config fully generic.
- Lots of Renesas SH-PFC incremental improvements"

Currently PINCTRL_IMX8QM and PINCTRL_IMX8QXP will select PINCTRL_IMX_SCU.
However, PINCTRL_IMX_SCU may not be valid due to it depends on IMX_MBOX.
Then we may meet the following link errors:

It's reasonable to expect that people turn to the "gpio" debugfs file to
first and foremost learn about the direction and value of a gpio, and
second to that about it's pinconf. So reorder the value so each line
reads:
gpioN: direction value ...
This also makes it consistent with the TLMM pinctrl driver's output in
the same dump.

The A80 SoC has configuration registers for I/O bias voltage. Incorrect
settings would make the affected peripherals inoperable in some cases,
such as Ethernet RGMII signals biased at 2.5V with the settings still
at 3.3V. However low speed signals such as MDIO on the same group of
pins seem to be unaffected.
Previously there was no way to know what the actual voltage used was,
short of hard-coding a value in the device tree. With the new pin bank
regulator supply support in place, the driver can now query the
regulator for its voltage, and if it's valid (as opposed to being the
dummy regulator), set the bias voltage setting accordingly.
Add a quirk to denote the presence of the configuration registers, and
a function to set the correct setting based on the voltage read back
from the regulator.
This is only done when the regulator is first acquired and enabled.
While it would be nice to have a notifier on the regulator so that when
the voltage changes, the driver can update the setting, in practice no
board currently supports dynamic changing of the I/O voltages.

SAM9X60 uses high and low drive strengths. To implement this, in
at91_pinctrl_mux_ops::set_drivestrength and
at91_pinctrl_mux_ops::get_drivestrength we need bit numbers of
drive strengths (1 for low, 2 for high), thus change the code to
allow the usage of drive strength bit numbers.

According to the datasheet, only JZ4780 have uart4 and i2c3/4. So we
remove it from the JZ4770 code and add a section corresponding the JZ4780.
Fix bugs in i2c0/1:
The pin number was wrong in the original code.
Fix bugs in uart2:
JZ4770 and JZ4780 have different uart2 pins. So the original section JZ4770
has been modified and the corresponding section of JZ4780 has been added.
Fix bugs in mmc0:
JZ4770 and JZ4780 assigned different pins to mmc0's 4~7 data lines. So the
original section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in mmc1:
JZ4770's mmc1 has 8bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in nemc:
JZ4770's nemc has 16bit mode, while JZ4780 doesn't. So the original section
JZ4770 has been modified and the corresponding section of JZ4780 has been
added. And add missing cs2~5 groups for JZ4770 and JZ4780.
Fix bugs in cim:
JZ4770's cim has 12bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in lcd:
Both JZ4770 and JZ4780 lcd should be 24bit instead of 32bit.

When declaring the HSPI RX1_B and TX1_B pins, two mistakes were made:
- the rows and columns in the BGA pin matrix, from which the pin
numbers are derived, were exchanged,
- it was not taken into account that pin row labelling skips
characters I, O, Q, and S.
Fix the order, and the corresponding pin names.
Notes:
- The actual values of the pin numbers don't really matter (they just
have to be unique), so the wrong order didn't have any impact,
- Changing the names of the pins is user-visible, but there are no
users in (upstream) DTS files.

The naming of the "b" versions of the VIN1 pin groups is a bit odd, in
that the "_b" appears in the middle of the names, instead of as a
suffix.
Increase consistency with other SoCs by making R-Car M2-W and M2-N, and
RZ/G1M and RZ/G1N, use the recently added optional "version" argument of
the VIN_DATA_PIN_GROUP() macro.
Note that this breaks backwards compatibility with existing DTBs, but
there are no upstream users of the "vin1_b_*" names.
