1* palmas regulator IP block devicetree bindings 2 3The tps659038 for the AM57x class have OTP spins that 4have different part numbers but the same functionality. There 5is not a need to add the OTP spins to the palmas driver. The 6spin devices should use the tps659038 as it's compatible value. 7This is the list of those devices: 8tps659037 9 10Required properties: 11- compatible : Should be from the list 12 ti,twl6035-pmic 13 ti,twl6036-pmic 14 ti,twl6037-pmic 15 ti,tps65913-pmic 16 ti,tps65914-pmic 17 ti,tps65917-pmic 18 ti,tps659038-pmic 19and also the generic series names 20 ti,palmas-pmic 21- interrupts : The interrupt number and the type which can be looked up here: 22 arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h 23- interrupts-name: The names of the individual interrupts. 24 25Optional properties: 26- ti,ldo6-vibrator : ldo6 is in vibrator mode 27 28Optional nodes: 29- regulators : Must contain a sub-node per regulator from the list below. 30 Each sub-node should contain the constraints and initialization 31 information for that regulator. See regulator.txt for a 32 description of standard properties for these sub-nodes. 33 Additional custom properties are listed below. 34 35 For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP, 36 smps45, smps457, smps7 depending on variant, smps6, smps[8-9], 37 smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb. 38 39 Optional sub-node properties: 40 ti,warm-reset - maintain voltage during warm reset(boolean) 41 ti,roof-floor - This takes as optional argument on platform supporting 42 the rail from desired external control. If there is no argument then 43 it will be assume that it is controlled by NSLEEP pin. 44 The valid value for external pins are: 45 ENABLE1 then 1, 46 ENABLE2 then 2 or 47 NSLEEP then 3. 48 ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto, 49 2 - eco, 3 - forced pwm 50 ti,smps-range - OTP has the wrong range set for the hardware so override 51 0 - low range, 1 - high range. 52 53- ti,system-power-controller: Telling whether or not this pmic is controlling 54 the system power. 55 56Example: 57 58#include <dt-bindings/interrupt-controller/irq.h> 59 60pmic { 61 compatible = "ti,twl6035-pmic", "ti,palmas-pmic"; 62 interrupt-parent = <&palmas>; 63 interrupts = <14 IRQ_TYPE_NONE>; 64 interrupts-name = "short-irq"; 65 66 ti,ldo6-vibrator; 67 68 ti,system-power-controller; 69 70 regulators { 71 smps12_reg : smps12 { 72 regulator-name = "smps12"; 73 regulator-min-microvolt = < 600000>; 74 regulator-max-microvolt = <1500000>; 75 regulator-always-on; 76 regulator-boot-on; 77 ti,warm-reset; 78 ti,roof-floor = <1>; /* ENABLE1 control */ 79 ti,mode-sleep = <0>; 80 ti,smps-range = <1>; 81 }; 82 83 ldo1_reg: ldo1 { 84 regulator-name = "ldo1"; 85 regulator-min-microvolt = <2800000>; 86 regulator-max-microvolt = <2800000>; 87 }; 88 }; 89}; 90
