Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux

Pull device tree updates from Grant Likely:
 "This branch contains the following changes:
   - Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
   - Remove #ifdef from linux/of_platform.h to increase compiler syntax
     coverage
   - Bug fix for address decoding on Bimini and js2x powerpc platforms.
   - miscellaneous binding changes

  One note on the above.  The binding changes going in from all kinds of
  different trees has gotten rather out of hand.  I picked up some
  during this cycle, but even going though my tree isn't a great fit.

  Ian Campbell has prototyped splitting the bindings and .dtb files into
  a separate repository.  The plan is to migrate to using that sometime
  in the next few kernel releases which should get rid of a lot of the
  churn on binding docs and .dts files"

* tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux:
  of: Fix address decoding on Bimini and js2x machines
  of: remove CONFIG_OF_DEVICE
  usb: chipidea: depend on CONFIG_OF instead of CONFIG_OF_DEVICE
  of: remove of_platform_driver
  ibmebus: convert of_platform_driver to platform_driver
  driver core: move to_platform_driver to platform_device.h
  mfd: DT bindings for the palmas family MFD
  ARM: dts: omap3-devkit8000: fix NAND memory binding
  of/base: fix typos
  of: remove #ifdef from linux/of_platform.h

+* palmas device tree bindings
+
+The TI palmas family current members :-
+twl6035 (palmas)
+twl6037 (palmas)
+tps65913 (palmas)
+tps65914 (palmas)
+
+Required properties:
+- compatible : Should be from the list
+  ti,twl6035
+  ti,twl6036
+  ti,twl6037
+  ti,tps65913
+  ti,tps65914
+  ti,tps80036
+and also the generic series names
+  ti,palmas
+- interrupt-controller : palmas has its own internal IRQs
+- #interrupt-cells : should be set to 2 for IRQ number and flags
+  The first cell is the IRQ number.
+  The second cell is the flags, encoded as the trigger masks from
+  Documentation/devicetree/bindings/interrupts.txt
+- interrupt-parent : The parent interrupt controller.
+
+Optional properties:
+  ti,mux-padX : set the pad register X (1-2) to the correct muxing for the
+		hardware, if not set will use muxing in OTP.
+
+Example:
+
+palmas {
+	compatible = "ti,twl6035", "ti,palmas";
+	reg = <0x48>
+	interrupt-parent = <&intc>;
+	interrupt-controller;

+
+	ti,mux-pad1 = <0>;
+	ti,mux-pad2 = <0>;
+
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	pmic {
+		compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
+		....
+	};

+* palmas regulator IP block devicetree bindings

+  ti,twl6036-pmic
+  ti,twl6037-pmic
+  ti,tps65913-pmic
+  ti,tps65914-pmic
+and also the generic series names
+  ti,palmas-pmic
+- interrupt-parent : The parent interrupt controller which is palmas.
+- interrupts : The interrupt number and the type which can be looked up here:
+	       arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
+- interrupts-name: The names of the individual interrupts.
+
+Optional properties:
+- ti,ldo6-vibrator : ldo6 is in vibrator mode
+
+Optional nodes:
+- regulators : Must contain a sub-node per regulator from the list below.
+	       Each sub-node should contain the constraints and initialization
+	       information for that regulator. See regulator.txt for a
+	       description of standard properties for these sub-nodes.
+	       Additional custom properties  are listed below.
+
+	       For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
+	       smps45, smps457, smps7 depending on variant, smps6, smps[8-10],
+	       ldo[1-9], ldoln, ldousb.
+
+	       Optional sub-node properties:
+	       ti,warm-reset - maintain voltage during warm reset(boolean)
+	       ti,roof-floor - control voltage selection by pin(boolean)
+	       ti,sleep-mode - mode to adopt in pmic sleep 0 - off, 1 - auto,
+	       2 - eco, 3 - forced pwm
+	       ti,tstep - slope control 0 - Jump, 1 10mV/us, 2 5mV/us, 3 2.5mV/us
+	       ti,smps-range - OTP has the wrong range set for the hardware so override
+	       0 - low range, 1 - high range.
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+pmic {
+	compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
+	interrupt-parent = <&palmas>;
