Convert sbs-battery bindings to YAML.

In certain designs, it is possible to add a battery on a populated i2c
bus without an sbs compliant charger. In that case, the battery will
unnecessarily and sometimes undesirably master the bus trying to write
info in the charger.
It is observed in many occasion that these battery "broadcasts" are even
corrupting other ongoing master to slave communication. I.e. the
multi-master support in the battery is inadequate.
Thankfully, the CHARGER_MODE bit allows designers to disable that SBS
battery behaviour.
This needs to be done once when the battery is first seen on the bus.

Add support for BQ20Z65 manufacturer data to the sbs-battery
driver. Implementation has been verified using the public TRM

Add:
- trickle-charge-current-microamp:
Some chargers have 3 charging stages. First one when battery is almost
empty is often called as trickle-charge. Last state when battery has been
"woken up" is usually called as fast-charge. In addition to this some
chargers have a 'middle state' which ROHM BD99954 data-sheet describes as
pre-charge. Some batteries can benefit from this 3-phase charging
[citation needed].
Introduce trickle-charge-current-microamp so that batteries can give
charging current limit for all three states.
- precharge-upper-limit-microvolt:
When battery voltage has reached certain limit we change from
trickle-charge to next charging state (pre-charge for BD99954). Allow
battery to specify this limit.
- re-charge-voltage-microvolt:
Allow giving a battery specific voltage limit for chargers which can
automatically re-start charging when battery has discharghed down to
this limit.
- over-voltage-threshold-microvolt
Allow specifying voltage threshold after which the battery is assumed to
be faulty.

lib: Add linear ranges helper library and start using it
Series extracts a "linear ranges" helper out of the regulator
framework. Linear ranges helper is intended to help converting
real-world values to register values when conversion is linear. I
suspect this is useful also for power subsystem and possibly for clk.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces SYSCON reboot-mode
legacy bare text bindings with YAML file. As before the bindings file
states that the corresponding dts node is supposed to be compatible
"syscon-reboot-mode" device and necessarily have an offset property
to determine which register from the regmap is supposed to keep the
mode on reboot.

The defaults listed in the bindings don't match what the code is
actually doing. Presumably existing users care more about keeping
existing behavior the same, so change the bindings to match the code
in Linux.
The "qcom,preemphasis-level" default has been wrong for quite a long
time (May 2018). The other two were recently added.
As some evidence that these values are wrong, this is from the Linux
driver:
- qcom,preemphasis-level: sets "PORT_TUNE1", lower 2 bits. Driver
programs PORT_TUNE1 to 0x30 by default and (0x30 & 0x3) = 0.
- qcom,bias-ctrl-value: sets "PLL_BIAS_CONTROL_2", lower 6 bits.
Driver programs PLL_BIAS_CONTROL_2 to 0x20 by default and (0x20 &
0x3f) = 0x20 = 32.
- qcom,hsdisc-trim-value: sets "PORT_TUNE2", lower 2 bits. Driver
programs PORT_TUNE2 to 0x29 by default and (0x29 & 0x3) = 1.

There's several cases of json-schema 'additionalProperties' at the wrong
indentation level which has the effect of making them DT properties. This
is harmless, but let's fix them so a meta-schema check for this can be
added.
In all the cases, either the 'additionalProperties' was extra or doesn't
work because there's a $ref to more properties. In the latter case, we
can use 'unevaluatedProperties' instead.

As the number of schemas has increased, we're starting to hit the error
"execvp: /bin/sh: Argument list too long". This is due to passing all the
schema files on the command line to dt-mk-schema. It currently is only
with out of tree builds and is intermittent depending on the file path
lengths.
Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made
hitting this proplem more likely since the example validation now always
gets the full list of schemas.
Fix this by passing the schema file list in a pipe and using xargs. We end
up doing the find twice, but the time is insignificant compared to the
dt-mk-schema time.

first for high speed devices")
Commit bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for
high speed devices") changed the way the hub driver enumerates
high-speed devices. Instead of using the "new" enumeration scheme
first and switching to the "old" scheme if that doesn't work, we start
with the "old" scheme. In theory this is better because the "old"
scheme is slightly faster -- it involves resetting the device only
once instead of twice.
However, for a long time Windows used only the "new" scheme. Zeng Tao
said that Windows 8 and later use the "old" scheme for high-speed
devices, but apparently there are some devices that don't like it.
William Bader reports that the Ricoh webcam built into his Sony Vaio
laptop not only doesn't enumerate under the "old" scheme, it gets hung
up so badly that it won't then enumerate under the "new" scheme! Only
a cold reset will fix it.
Therefore we will revert the commit and go back to trying the "new"
scheme first for high-speed devices.

the core schemas (from dtschema repo) were inadvertently disabled for
dtbs_checks. Re-enable them.

ASoC: Fixes for v5.7
Quite a lot of fixes here, a lot of driver specific ones but the biggest
one is the revert of changes to the startup and shutdown sequence for
DAIs that went in during the merge window - they broke some older x86
platforms and attempts to fix them didn't succeed so it's safer to just
roll them back and try to make sure those platforms are handled properly
in any future attempt.
The rockchip S/PDIF DT stuff was IIRC for validation issues.

First set of IIO fixes for the 5.7 cycle.
Includes one MAINTAINERS update to avoid people getting a lot of bounce
messages and complaining about it.
* MAINTAINERS
- Drop Stefan Popa's Analog Devices email address in favour of
Michael Hennerich.
* core
- Fix handling of dB sysfs inputs.
- Drop a stray semi colon in macro definition.
* ad5770r
- Fix an off by one in chec on maximum number of channels.
* ad7192
- Fix a null pointer de-reference due to the name previously being
retrieved from the spi_get_device_id call which no longer works as
the relevant table was removed.
* ad7797
- Use correct attribute group.
* counter/104-quad-8
- Add locks to prevent some race conditions.
* inv-mpu6050
- Fix issues around suspend / resume clashing with runtime PM.
* stm32-adc
- Fix sleep in invalid context
- Fix id relative path error in device tree binding doc.
* st_lsm6dsx
- Fix a read alignment issue on an untagged FIFO.
- Handle odr for slave to properly compute the FIFO data layout / pattern.
- Flush the HW FIFO before resettting the device to avoid a race on
interrupt line 1.
* st_sensors
- Rely on ODR mask not ODR address to identify if the ODR can be set.
Some devices have an ODR address of 0.
* ti-ads8344
- Byte ordering was wrong - fix it.
* xilinx-xadc
- Fix inverted logic in powering down the second ADC.
- Fix clearing interrupt when enabling the trigger.
- Fix configuration of sequencer when in simultaneous sampling mode.
- Limit initial sampling rate as done for runtime configured ones.

No one checks the return value of debugfs_create_u32(), as it's not
needed, so make the return value void, so that no one tries to do so in
the future.
