Greg Kroah-Hartman 1c4ccab04a Merge tag 'iio-for-4.20b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:

Second set of IIO new device support features and cleanup for the 4.20 cycle.

One merge commit in here to bring in the SPI_CS_WORD flag patches
that are also going via the SPI tree.

There are a few more fixes than normal for a pull targetting the
next merge window.  These are all long term issues and as we are late
in the cycle, they can wait.

New device support
* ad7606
  - Add support fo the ad7605-4 driver.  This driver is still in staging
    but is heading in the right direction to graduate, motivated partly
    by the requirement for this device support.
* ST VL53L0X ToF ranging sensor
  - New minimal driver. Interrupt support to follow.

New features

* SPI_CS_WORD optimization allows long transfers with the chip select
  toggled every 16bits.   There is a software fallback as well to let
  drivers not care about whether the hardware supports it.

* bh1750
  - Device tree support and bindings.
* ti-ads7950
  - Use the SPI_CS_WORD optmization to save lots of cpu cycles (assuming
    the hardware supports it)

Fixes and cleanups

* ad5064
  - Fix some long incorrect regulator error handling that preventing
    enabling the internal regulator.
* ad7606
  - The ad7606 doesn't actually have a 2.5V range and the values provided
    for scale have always been wrong.  Fix them.
  - Drop some wrong kernel-doc (things that don't exist)
  - Add missing kernel-doc
* at91-adc
  - Fixing missing ack of dataready on sysfs channel reads to avoid spurious
    interrupts.
  - Fix a wrong channel numbers in triggered_buffer_mode
* hmc5843
  - Fix incorrect part number in a comment.
* imx25-gcq
  - Fix a device_node leak in an error path.
* meson-saradc
  - Drop an unused and pointless define.
  - Use of_device_get_match_data instead of opencoding
  - Tidy up how meson_sar_adc_param is accessed.
  - Rework prior to adding some temperature sensor support.
