Greg Kroah-Hartman 1c4ccab04a 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.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
