Merge tag 'staging-4.12-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 tree update for 4.12-rc1.

  It's a big one, adding about 350k new lines of crap^Wcode, mostly all
  in a big dump of media drivers from Intel. But there's other new
  drivers in here as well, yet-another-wifi driver, new IIO drivers, and
  a new crypto accelerator.

  We also deleted a bunch of stuff, mostly in patch cleanups, but also
  the Android ION code has shrunk a lot, and the Android low memory
  killer driver was finally deleted, much to the celebration of the -mm
  developers.

  All of these have been in linux-next with a few build issues that will
  show up when you merge to your tree"

Merge conflicts in the new rtl8723bs driver (due to the wifi changes
this merge window) handled as per linux-next, courtesy of Stephen
Rothwell.

+* Devantech SRF04 ultrasonic range finder
+  Bit-banging driver using two GPIOs
+
+Required properties:
+ - compatible:	Should be "devantech,srf04"
+
+ - trig-gpios:	Definition of the GPIO for the triggering (output)
+		This GPIO is set for about 10 us by the driver to tell the
+		device it should initiate the measurement cycle.
+
+ - echo-gpios:	Definition of the GPIO for the echo (input)
+		This GPIO is set by the device as soon as an ultrasonic
+		burst is sent out and reset when the first echo is
+		received.
+		Thus this GPIO is set while the ultrasonic waves are doing
+		one round trip.
+		It needs to be an GPIO which is able to deliver an
+		interrupt because the time between two interrupts is
+		measured in the driver.
+		See Documentation/devicetree/bindings/gpio/gpio.txt for
+		information on how to specify a consumer gpio.
+
+Example:
+srf04@0 {
+	compatible = "devantech,srf04";
+	trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
+	echo-gpios = <&gpio2  6 GPIO_ACTIVE_HIGH>;
+};
