Exynos4212 and Exynos4412 have only four ADC channels so using
"samsung,exynos-adc-v1" compatible (for eight channels ADCv1) on them is
wrong. Add a new compatible for Exynos4x12.

Meson8b and Meson8m2 use a 5-bit wide TSC (temperature sensor
coefficient). The SAR ADC registers however can only store (the lower)
4 bits. The fifth (upper-most) bit is stored inside the
MESON_HHI_DPLL_TOP_0[9] register from the HHI register area.
This adds a syscon property to the HHI register area so a driver can
fetch the HHI register map and store the fifth TSC bit in there.

As usual, this is where the bulk of our changes end up landing each
merge window.
The individual updates are too many to enumerate, many many platforms
have seen additions of device descriptions such that they are
functionally more complete (in fact, this is often the bulk of updates
we see).
Instead I've mostly focused on highlighting the new platforms below as
they are introduced. Sometimes the introduction is of mostly a fragment,
that later gets filled in on later releases, and in some cases it's
near-complete platform support. The latter is more common for derivative
platforms that already has similar support in-tree.
Two SoCs are slight outliers from the usual range of additions. Allwinner
support for F1C100s, a quite old SoC (ARMv5-based) shipping in the
Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A,
a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at
infrastructure/networking.
TI updates stick out in the diff stats too, in particular because they
have moved the description of their L4 on-chip interconnect to devicetree,
which opens up for removal of even more of their platform-specific
'hwmod' description tables over the next few releases.
SoCs:
- Qualcomm QCS404 (4x Cortex-A53)
- Allwinner T3 (rebranded R40) and f1c100s (armv5)
- NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)
- NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72)

good, tiny cleanups is nice to see. No new huge driver removal or
addition, this release cycle, although there are lots of good IIO driver

There are several ADC drivers that depend on the same device tree

adds a common adc binding document that can be referenced. For beginning,
only two properties are documented.

The node has a reg property, therefore its name should include a unit
address. Also change the name from 'usb_id_nopull' to 'adc-chan', which
is the preferred name for ADC channel nodes.
Include headers for constants used in the example.

The 32-bit Meson8 SoC can use the SAR ADC to read the chip temperature.
This requires setting the correct TSC (temperature sensor coefficient),
which is programmed into the eFuse during the manufacturing process.
Meson8b and Meson8m2 are not supported yet because they have a 5-bit TSC
and only the first four bits are stored inside the SAR ADC registers.

This driver was originally written by ST in 2016 as a misc input device
driver, and hasn't been maintained for a long time. I grabbed some code
from it's API and reformed it into an iio proximity device driver.
This version of driver uses i2c bus to talk to the sensor and
polling for measuring completes, so no irq line is needed.
It can be tested with reading from
/sys/bus/iio/devices/iio:deviceX/in_distance_input

There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs). Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.
New device support
* Analog devices ADXL372 accelerometer
- new driver for this accelerometer including fifo and and interrupt support.
Follow up patches enforce trigger validation, add sampling frequency
control and filter bandwidth control. A later series added i2c support
to the existing SPI support.
* ST lsm6dsx
- rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC
- new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
* Microchip mcp3911 ADC.
- new driver for this integrated analog front end and ADC.
* Qualcomm SPMI PMIC5 adc driver

Follow up patch adds some missing channels.
Features
* ad5758
- support hard reset using a gpio (if provided).
* mpu6050
- Regulator support
* qcom-spmi-adc5
- Sanity check the channel numbers provided by DT to make sure the
driver actually knows about them.
* sc27xx
- give raw data for channel 20 as it's used on all known boards for
the headset which needs a custom converstion function. If it turns
out someone builds a board where this isn't true we will deal with it
when it happens.
- add ADC scale calibration.
* tsl2772
- support device tree binding to set the proximity led settings.
- regulator supprot.
- binding for apds9930 - trivial addition as register compatible with tsl2772.
Cleanups / Minor fixes

object is null.

16 to get the shift.
- rework to share handing for oversampling of the various channels in a
unified way.
- check explicitly for val2 in write_raw function to ensure it is 0.

The documentation of Qualcomm's SPMI PMIC voltage ADC claims that the
'reg' property consists of two values, the SPMI address and the length
of the controller's registers. However the SPMI bus to which it is added
specifies "#size-cells = <0>;". Remove the controller register length
from the documentation of the field and the example.

The ad5758 has a hardware reset active low input pin. This patch adds a
devicetree entry for a reset GPIO and a new ad5758_reset() function.
During
initialization, it is checked if the reset property is specified and the
the GPIO is being asserted, therefore the device will become active.
When the reset function is called, if the gpio_reset var is set, then
the
GPIO will be toggled, otherwise a software reset is performed.
