Merge tag 'staging-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here is the big staging/iio driver pull request for 5.1-rc1.

  Lots of good IIO driver updates and cleanups in here as always.
  Combined with the removal of the xgifb driver, we have a net "loss" of
  over 9000 lines in the pull request, always a nice thing.

  As the outreachy application process is currently happening, there are
  loads of tiny checkpatch cleanup fixes all over the staging tree,
  which accounts for the majority of the fixups"

+Analog Devices AD7606 Simultaneous Sampling ADC
+
+Required properties for the AD7606:

+- compatible: Must be one of
+	* "adi,ad7605-4"
+	* "adi,ad7606-8"
+	* "adi,ad7606-6"
+	* "adi,ad7606-4"
+- reg: SPI chip select number for the device
+- spi-max-frequency: Max SPI frequency to use
+	see: Documentation/devicetree/bindings/spi/spi-bus.txt
+- spi-cpha: See Documentation/devicetree/bindings/spi/spi-bus.txt
+- avcc-supply: phandle to the Avcc power supply
+- interrupts: IRQ line for the ADC
+	see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+- adi,conversion-start-gpios: must be the device tree identifier of the CONVST pin.
+		  This logic input is used to initiate conversions on the analog
+		  input channels. As the line is active high, it should be marked
+		  GPIO_ACTIVE_HIGH.
+
+Optional properties:
+
+- reset-gpios: must be the device tree identifier of the RESET pin. If specified,
+	       it will be asserted during driver probe. As the line is active high,
+	       it should be marked GPIO_ACTIVE_HIGH.
+- standby-gpios: must be the device tree identifier of the STBY pin. This pin is used
+		to place the AD7606 into one of two power-down modes, Standby mode or
+		Shutdown mode. As the line is active low, it should be marked
+		GPIO_ACTIVE_LOW.
+- adi,first-data-gpios: must be the device tree identifier of the FRSTDATA pin.
+		    The FRSTDATA output indicates when the first channel, V1, is
+		    being read back on either the parallel, byte or serial interface.
+		    As the line is active high, it should be marked GPIO_ACTIVE_HIGH.
+- adi,range-gpios: must be the device tree identifier of the RANGE pin. The polarity on
+	      this pin determines the input range of the analog input channels. If
+	      this pin is tied to a logic high, the analog input range is ±10V for
+	      all channels. If this pin is tied to a logic low, the analog input range
+	      is ±5V for all channels. As the line is active high, it should be marked
+	      GPIO_ACTIVE_HIGH.
+- adi,oversampling-ratio-gpios: must be the device tree identifier of the over-sampling
+				mode pins. As the line is active high, it should be marked
+				GPIO_ACTIVE_HIGH.
