The device is always in a low-power state due to the hardware design. It
wakes up upon a conversion request and goes back into the low-power
state. The pm ops are added to disable the device completely and to free
the regulator. Disbaling the device completely should be not that
notable but freeing the regulator is important. Because if it is a shared
power-rail the regulator won't be disabled during suspend-to-ram/disk
and so all devices connected to that rail keeps on.

commit f7072198f2 ("iio: imu: Fix inv_mpu6050 dependencies")
undid the explicit selection of I2C_MUX previously
done by the driver, because I2C_MUX implicitly depended
on HAS_IOMEM.
However commit 93d710a65e ("i2c: mux: fix up dependencies")
cleared up the situation properly and drivers that need
to select I2C_MUX can now do so again.
It makes a lot of sense for a driver to select the driver
infrastructure it needs so restore the natural order of
things.

Add support for parallax ping and laser ping sensors with just one pin

This driver is based on srf04. In contrast to it it's necessary to
change direction of the pin and to request the irq just for the period

there is this individual driver for handling this type of sensors.

We added a sysfs ABI for getting/setting the type of a thermocouple. This
driver supports chips that support specific fixed thermocouple types; we
cannot set it, but still we can add this sysfs attribute in RO mode to
read-back the thermocouple type.
This driver supports actually several chips:
- max6675
- max31855[k/j/n/s/t/e/r]asa family
Max6675 supports only K-type thermocouples, so we can just report that.
Each chip in max31855 family supports just one specific thermocouple type
(in the obvious way: i.e. max31855jasa supports J-type). This driver did
accept a generic SPI ID and OF compatible "max31855" which does not give
any clue about which chip is really involved (and unfortunately it seems
we have no way to detect it).
This patch introduces a new set of, more specific, SPI IDs and OF
compatible strings to better match the chip type.
The old, generic, "max31855" binding is kept for compatibility reasons, but
this patch aims to deprecate it, so, should we hit it, a warning is spit.
In such case the reported thermocouple type in sysfs is '?', because we
have no way to know.
Regarding the implementation: the thermocouple type information is stored
in the driver private data and I've kept only two maxim_thermocouple_chip
types in order to avoid a lot of duplications (seven chip types with just
a different thermocouple type).
RFT because I have no real HW to test this.

The sensor support various thermocouple types (e.g. J, K, N, ...). The
driver allows to configure this parameter using a DT property.
This is useful when i.e. the thermocouple is physically tied to the sensor
and it is usually not removed, or when it is at least known in advance
which sensor will be connected to the circuit.
However, if the user can randomly connect any kind of thermocouples (i.e.
the device exposes a connector, and the user is free to connect its own
sensors), it would be more appropriate to provide a mechanism to
dynamically switch from one thermocouple type to another. This can be i.e.
handled in userspace by a GUI, a configuration file or a program that
detects the thermocouple type by reading a GPIO, or a eeprom on the probe,
or whatever.
This patch adds a IIO attribute that can be used to override, at run-time,
the DT-provided setting (which serves as default).

This patch introduces IIO_VAL_CHAR type for standard IIO attributes to
allow for attributes that needs to be represented by character rather
than a number. This is preparatory for introducing a new attribute whose
purpose is to describe thermocouple type, that can be i.e. "J", "K", etc..
The char-type value is stored in the first "value" integer that is passed
to the .[read/write]_raw() callbacks.
Note that in order to make it possible for the IIO core to correctly parse
this type (actually, to avoid integer parsing), it became mandatory for
any driver that wish to use IIO_VAL_CHAR on a writable attribute to
implement .write_raw_get_fmt().

This sensor has an embedded notch filter for reducing interferences caused
by the power mains. This filter can be tuned to reject either 50Hz or 60Hz
(and harmonics).
Currently the said setting is left alone (the sensor defaults to 60Hz).
This patch introduces a IIO attribute that allows the user to set the said
filter to the desired frequency.
NOTE: this has been intentionally not tied to any DT property to allow
the configuration of this setting from userspace, e.g. with a GUI or by
reading a configuration file, or maybe reading a GPIO tied to a physical
switch or accessing some device that can autodetect the line frequency.
