Device tree updates for v3.11

Browse Source 
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.

* 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;
#interrupt-cells = <2>;
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
Required properties:
- compatible : Should be from the list
ti,twl6035-pmic
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>;
interrupts = <14 IRQ_TYPE_NONE>;
interrupts-name = "short-irq";
ti,ldo6-vibrator;
regulators {
smps12_reg : smps12 {
regulator-name = "smps12";
regulator-min-microvolt = < 600000>;
regulator-max-microvolt = <1500000>;
regulator-always-on;
regulator-boot-on;
ti,warm-reset;
ti,roof-floor;
ti,mode-sleep = <0>;
ti,tstep = <0>;
ti,smps-range = <1>;
};
ldo1_reg: ldo1 {
regulator-name = "ldo1";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
};
};
