Second set of new device support, features and cleanup for IIO in the 5.1 cycle.
There are a few late breaking fixes in here that weren't worth trying to
rush into 5.0 as they have been with us for quite a while.
New device support
* ad7476
- add support for TI ADS786X parts that are compatible with this Analog
Devices driver. Good to see some simple devices are so similar.
* Ingenic jz47xx SoC ADCs
- new driver and bindings
* Plantower PMS7003 partical sensor
- new driver and bindings including vendor prefix.
* TI DAC7612
- new driver and bindings for this dual DAC.
New features
* ad7768-1
- Sampling frequency control
* bmi160
- Data ready trigger support, including open-drain dt binding.
Cleanup / minor fixes.
* Analog Device DACs
- Fix some inconsistent licenses. These are only ones where there were
two different license marked in the same file, and hence were previously
unclear.
* ads124s08
- Spelling fix.
* adxl345
- Parameter alignement tidy up.
* bmi160
- SPDX
- correct a note on the types of supported interrupts which was too strict.
- use iio_pollfunc_store_time to grab an earlier timestamp.
- use if (ret) instead of if (ret < 0) to be consistent whilst simplifying
some handling where ret was effectively getting written to 0 even though
it was always already 0.
* exynos_adc
- Fix a null pointer dereference on unbind.
- Fix number of channels on Exynos4x12 devices to be 4 rather than 8.
* lpc32xx-adc
- Move DT bindings doc out of staging. Oops, I missed this one when
moving the driver.
- SPDX.
* npcm-adc
- drop documentation of reset node as going to be done differently.
It's a new driver this cycle so no need to support the previous
binding going forwards.
* sps30
- Fix an issue with a loop timeout test that meant it would never identify
a timeout.
- Mark deliberate switch fall throughs.
* tag 'iio-for-5.1b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (26 commits)

wrong. Add a new compatible for Exynos4x12.

set_pmd_at() calls native_set_pmd() unconditionally on x86. This was
fine as long as only huge page entries were written via set_pmd_at(),
as Xen pv guests don't support those.
Commit 2c91bd4a4e ("mm: speed up mremap by 20x on large regions")
introduced a usage of set_pmd_at() possible on pv guests, leading to
failures like:

- A workaround for a Loongson 3 CPU bug is the biggest change, but

atomicity.
- Loongson64 also sees a fix for powering off some systems which
would incorrectly reboot rather than waiting for the power down
sequence to complete.
- We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
board, and a DT warning fix for the Nexsys4/MIPSfpga board.
- The Cavium Octeon platform sees a further fix to the behaviour of
the pcie_disable command line argument that was introduced in v3.3.
- The VDSO, introduced in v4.4, sees build fixes for configurations
of GCC that were built using the --with-fp-32= flag to specify a
default 32-bit floating point ABI.
- get_frame_info() sees a fix for configurations with
CONFIG_KALLSYMS=n, for which it previously always returned an
error.
- If the MIPS Coherence Manager (CM) reports an error then we'll now
clear that error correctly so that the GCR_ERROR_CAUSE register
will be updated with information about any future errors"

The AD7768-1 core ADC receives a master clock signal (MCLK). The MCLK
frequency combined with the MCLK division and the digital filter
decimation rates, determines the sampling frequency. Along with
MCLK_DIV, the power mode is also configured according to datasheet
recommendations.
From user space, available sampling frequencies can be read. However,
it is not required for an exact value to be entered, since the driver
will look for the closest available match.
When the device configuration changes (for example, if the filter
decimation rate changes), a SYNC_IN pulse is required.
