Convert the Hisilicon Hi6220 domain controllers binding to DT schema
format using json-schema. All of them are grouped into one yaml file, to
help users understand differences and avoid repeated descriptions.

There are two vendor prefixes for Gateworks: "gw" and "gateworks".
Favor the longer one (more descriptive) and mark "gw" as deprecated so
it will not be used in new bindings.

Update the AM65x HwSpinlock example to fix couple of warnings
that started showing up after the conversion of K3 bindings to
YAML format in commit 66e06509aa ("dt-bindings: arm: ti:
Convert K3 board/soc bindings to DT schema").
compatible: ['ti,am654'] is not valid under any of the given schemas (Possible causes of the failure):
compatible: ['ti,am654'] is too short
compatible:0: 'ti,am654' is not one of ['ti,am654-evm']
Also, fix one of the node names while at this.

This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC
chip connects to a set of sensor chips to monitor current, voltage,
thermal and power of different components on board. The BMC firmware is
responsible for sensor data sampling and recording in shared registers.
Host driver reads the sensor data from these shared registers and
exposes them to users as hwmon interfaces.

Output defects can exist in sysfs content using sprintf and snprintf.
sprintf does not know the PAGE_SIZE maximum of the temporary buffer
used for outputting sysfs content and it's possible to overrun the
PAGE_SIZE buffer length.
Add a generic sysfs_emit function that knows that the size of the
temporary buffer and ensures that no overrun is done.
Add a generic sysfs_emit_at function that can be used in multiple
call situations that also ensures that no overrun is done.
Validate the output buffer argument to be page aligned.

GX20MH01 device shares family number 0x28 with DS18B20. The device
is generally compatible with DS18B20. Added are the lowest 2^-5, 2^-6
temperature bits in Config register; R2 bit in Config register
enabling 13 and 14 bit resolutions. It is powered up in 14 bit mode.

The conversion time of common DS18B20 clones deviates from
datasheet specs. Allow adjustment and automatic measure of the
conversion time.
Add 'conv_time' sysfs attribute:
*read*: Current conversion time in milliseconds.
*write*:
'0': Set default conversion time.
'1': Measure and set the conversion time. Make a
single temperature conversion, poll and measure
an actual value. Measured value is increased
by 20% for temperature drift. A new conversion
time is returned by reading the same attribute.
other positive value:
Set the conversion time in milliseconds.
The setting is active until a resolution change. Then it is reset to
default conversion time for a new resolution.
Add 'features' sysfs attribute to control optional driver settings
per device. Bit masks to read/write (logical OR):
1: Enable check for conversion success. If byte 6 of
scratchpad memory is 0xC after conversion, and
temperature reads 85.00 (powerup value) or 127.94
(insufficient power) - return a conversion error.
2: Enable poll for conversion completion. Generate read cycles
after the conversion start and wait for 1's. In parasite
power mode this feature is not available.
There are some clones of DS18B20 with fixed 12 bit resolution. Make the
driver verify the resolution by reading back the device after resolution
change.

Introduce sysfs entries to enable userspace clients the ability to read
the serial number and the OEM PK Hash values obtained from BHI. OEMs
need to read these device-specific hardware information values through
userspace for factory testing purposes and cannot be exposed via degbufs
as it may remain disabled for performance reasons. Also, update the
documentation for ABI to include these entries.

At Hikey 970, setting the SPLIT disable at the General
User Register 3 is required.
Without that, the URBs generated by the usbhid driver
return -EPROTO errors. That causes the code at
hid-core.c to call hid_io_error(), which schedules
a reset_work, causing a call to hid_reset().
In turn, the code there will call:
usb_queue_reset_device(usbhid->intf);
The net result is that the input devices won't work, and

These are simple defines so they could be used in DTS but they will not

This patch implements the basic functions of the BMC chip for some Intel
FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the
Intel MAX 10 CPLD.
This BMC chip is connected to the FPGA by a SPI bus. To provide direct
register access from the FPGA, the "SPI slave to Avalon Master Bridge"
(spi-avmm) IP is integrated in the chip. It converts encoded streams of
bytes from the host to the internal register read/write on the Avalon
bus. So This driver uses the regmap-spi-avmm for register accessing.

CONFIG_EFI_VARS controls the code that exposes EFI variables via
sysfs entries, which was deprecated before support for non-Intel
architectures was added to EFI. So let's limit its availability
to Intel architectures for the time being, and hopefully remove
it entirely in the not too distant future.
While at it, let's remove the module alias so that the module is
no longer loaded automatically.

This binding is non trivial due to the range of different parts
supported having several subtle quirks. Martin has helped
clarify some of them.
Note, I haven't restricted the amlogic,hhi-sysctrl to only
be present on the relevant parts if nvmem stuff also is, but
it would seem to be rather odd if it were otherwise.
Perhaps we look to make this binding more restrictive at a later date.

There are behavioural requirements on the seq_file next() function in
terms of how it updates *pos at end-of-file, and these are now enforced
by a warning.
I was recently attempting to justify the reason this was needed, and
couldn't remember the details, and didn't find them in the
documentation.
So I re-read the code until I understood it again, and updated the
documentation to match.
I also enhanced the text about SEQ_START_TOKEN as it seemed potentially
misleading.

Initial driver for PMU event counting on the Arm CMN-600 interconnect.
CMN sports an obnoxiously complex distributed PMU system as part of
its debug and trace features, which can do all manner of things like
sampling, cross-triggering and generating CoreSight trace. This driver
covers the PMU functionality, plus the relevant aspects of watchpoints
for simply counting matching flits.

The MIPI DisCo device properties that are read by the driver from
platform firmware, or hard-coded in the driver, should only be
provided as sysfs entries when a driver probes successfully.
However the device status and device number is updated even when there
is no driver present, and hence can be updated when a Slave device is
detected on the bus without being described in platform firmware and
without any driver registered/probed.
As suggested by GregKH, the attribute group for Slave status and
device number is is added by default upon device registration.
Credits to Vinod Koul for the status_show() function, shared in a
separate patch and used as is here. The status table was modified to
remove an unnecessary enum and status_show() is handled in a different
group attribute than what was suggested by Vinod.
