[PATCH] mfd: DT bindings for the palmas family MFD

[J Keerthy]

From: Graeme Gregory <gg@xxxxxxxxxxxxxxx> 

Add the various binding files for the palmas family of chips. There is a
top level MFD binding then a seperate binding for regulators IP blocks on chips.

+* 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

+  ti,twl6037-pmic

+
+Optional properties:
+- ti,ldo6-vibrator : ldo6 is in vibrator mode
+
+Optional nodes:
+- regulators : should contain the constrains and init information for the
+	       regulators. It should contain a subnode per regulator from the
+	       list.
+	       For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
+	       smps45, smps457, smps7 depending on varient, smps6, smps[8-10],
+	       ldo[1-9], ldoln, ldousb
+
+	       optional chip specific regulator fields :-
+	       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
