Subject[PATCH v2] mfd: DT bindings for the palmas family MFD
Date
From: Graeme Gregory <gg@slimlogic.co.uk>

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.

Changes from v1:
* Corrected ti,ldo6_vibrator property ---> ti,ldo6-vibrator
* Added the irq.h header file inclusion for defining type of interrupt

+* 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
+
+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
+
+Example:
+
+#include <include/dt-bindings/interrupt-controller/irq.h>
+
+pmic {
+ compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
+ interrupt-parent = <&palmas>;
+ interrupts = <14 IRQ_TYPE_NONE>;
+ interrupt-name = "short-irq";
+
+ ti,ldo6-vibrator;
+
+ regulators {
+ smps12_reg : smps12 {
+ regulator-name = "smps12";
+ regulator-min-microvolt = < 600000>;

+ 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>;
+ };
+ };
+};
