Pull devicetree updates from Rob Herring:
 "DT Bindings:

   - Various LED binding conversions and clean-ups. Convert the
     ir-spi-led, pwm-ir-tx, and gpio-ir-tx LED bindings to schemas.
     Consistently reference LED common.yaml or multi-led schemas and
     disallow undefined properties.

   - Convert IDT 89HPESx, pwm-clock, st,stmipid02, Xilinx PCIe hosts,
     and fsl,imx-fb bindings to schema

   - Add ata-generic, Broadcom u-boot environment, and dynamic MTD
     sub-partitions bindings.

   - Make all SPI based displays reference spi-peripheral-props.yaml

   - Fix some schema property regex's which should be fixed strings or
     were missing start/end anchors

   - Remove 'status' in examples, again...

  DT Core:

   - Fix a possible NULL dereference in overlay functions

   - Fix kexec reading 32-bit "linux,initrd-{start,end}" values (which
     never worked)

   - Add of_address_count() helper to count number of 'reg' entries

   - Support .dtso extension for DT overlay source files. Rename staging
     and unittest overlay files.

   - Update dtc to upstream v1.6.1-63-g55778a03df61"

-Binding for an external clock signal driven by a PWM pin.
-
-This binding uses the common clock binding[1] and the common PWM binding[2].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-[2] Documentation/devicetree/bindings/pwm/pwm.txt
-
-Required properties:
-- compatible : shall be "pwm-clock".
-- #clock-cells : from common clock binding; shall be set to 0.
-- pwms : from common PWM binding; this determines the clock frequency
-  via the period given in the PWM specifier.
-
-Optional properties:
-- clock-output-names : From common clock binding.
-- clock-frequency : Exact output frequency, in case the PWM period
-  is not exact but was rounded to nanoseconds.
-
-Example:
-	clock {
-		compatible = "pwm-clock";
-		#clock-cells = <0>;
-		clock-frequency = <25000000>;
-		clock-output-names = "mipi_mclk";
-		pwms = <&pwm2 0 40>; /* 1 / 40 ns = 25 MHz */
-	};
