1* Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC) 2 3Required properties: 4- compatible : Should be "fsl,mc13783" or "fsl,mc13892" 5 6Optional properties: 7- fsl,mc13xxx-uses-adc : Indicate the ADC is being used 8- fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used 9- fsl,mc13xxx-uses-rtc : Indicate the RTC is being used 10- fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used 11 12Sub-nodes: 13- codec: Contain the Audio Codec node. 14 - adc-port: Contain PMIC SSI port number used for ADC. 15 - dac-port: Contain PMIC SSI port number used for DAC. 16- leds : Contain the led nodes and initial register values in property 17 "led-control". Number of register depends of used IC, for MC13783 is 6, 18 for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of 19 these registers. 20 - #address-cells: Must be 1. 21 - #size-cells: Must be 0. 22 Each led node should contain "reg", which used as LED ID (described below). 23 Optional properties "label" and "linux,default-trigger" is described in 24 Documentation/devicetree/bindings/leds/common.txt. 25- regulators : Contain the regulator nodes. The regulators are bound using 26 their names as listed below with their registers and bits for enabling. 27 28MC13783 LED IDs: 29 0 : Main display 30 1 : AUX display 31 2 : Keypad 32 3 : Red 1 33 4 : Green 1 34 5 : Blue 1 35 6 : Red 2 36 7 : Green 2 37 8 : Blue 2 38 9 : Red 3 39 10 : Green 3 40 11 : Blue 3 41 42MC13892 LED IDs: 43 0 : Main display 44 1 : AUX display 45 2 : Keypad 46 3 : Red 47 4 : Green 48 5 : Blue 49 50MC34708 LED IDs: 51 0 : Charger Red 52 1 : Charger Green 53 54MC13783 regulators: 55 sw1a : regulator SW1A (register 24, bit 0) 56 sw1b : regulator SW1B (register 25, bit 0) 57 sw2a : regulator SW2A (register 26, bit 0) 58 sw2b : regulator SW2B (register 27, bit 0) 59 sw3 : regulator SW3 (register 29, bit 20) 60 vaudio : regulator VAUDIO (register 32, bit 0) 61 viohi : regulator VIOHI (register 32, bit 3) 62 violo : regulator VIOLO (register 32, bit 6) 63 vdig : regulator VDIG (register 32, bit 9) 64 vgen : regulator VGEN (register 32, bit 12) 65 vrfdig : regulator VRFDIG (register 32, bit 15) 66 vrfref : regulator VRFREF (register 32, bit 18) 67 vrfcp : regulator VRFCP (register 32, bit 21) 68 vsim : regulator VSIM (register 33, bit 0) 69 vesim : regulator VESIM (register 33, bit 3) 70 vcam : regulator VCAM (register 33, bit 6) 71 vrfbg : regulator VRFBG (register 33, bit 9) 72 vvib : regulator VVIB (register 33, bit 11) 73 vrf1 : regulator VRF1 (register 33, bit 12) 74 vrf2 : regulator VRF2 (register 33, bit 15) 75 vmmc1 : regulator VMMC1 (register 33, bit 18) 76 vmmc2 : regulator VMMC2 (register 33, bit 21) 77 gpo1 : regulator GPO1 (register 34, bit 6) 78 gpo2 : regulator GPO2 (register 34, bit 8) 79 gpo3 : regulator GPO3 (register 34, bit 10) 80 gpo4 : regulator GPO4 (register 34, bit 12) 81 pwgt1spi : regulator PWGT1SPI (register 34, bit 15) 82 pwgt2spi : regulator PWGT2SPI (register 34, bit 16) 83 84MC13892 regulators: 85 vcoincell : regulator VCOINCELL (register 13, bit 23) 86 sw1 : regulator SW1 (register 24, bit 0) 87 sw2 : regulator SW2 (register 25, bit 0) 88 sw3 : regulator SW3 (register 26, bit 0) 89 sw4 : regulator SW4 (register 27, bit 0) 90 swbst : regulator SWBST (register 29, bit 20) 91 vgen1 : regulator VGEN1 (register 32, bit 0) 92 viohi : regulator VIOHI (register 32, bit 3) 93 vdig : regulator VDIG (register 32, bit 9) 94 vgen2 : regulator VGEN2 (register 32, bit 12) 95 vpll : regulator VPLL (register 32, bit 15) 96 vusb2 : regulator VUSB2 (register 32, bit 18) 97 vgen3 : regulator VGEN3 (register 33, bit 0) 98 vcam : regulator VCAM (register 33, bit 6) 99 vvideo : regulator VVIDEO (register 33, bit 12) 100 vaudio : regulator VAUDIO (register 33, bit 15) 101 vsd : regulator VSD (register 33, bit 18) 102 gpo1 : regulator GPO1 (register 34, bit 6) 103 gpo2 : regulator GPO2 (register 34, bit 8) 104 gpo3 : regulator GPO3 (register 34, bit 10) 105 gpo4 : regulator GPO4 (register 34, bit 12) 106 pwgt1spi : regulator PWGT1SPI (register 34, bit 15) 107 pwgt2spi : regulator PWGT2SPI (register 34, bit 16) 108 vusb : regulator VUSB (register 50, bit 3) 109 110 The bindings details of individual regulator device can be found in: 111 Documentation/devicetree/bindings/regulator/regulator.txt 112 113Examples: 114 115ecspi@70010000 { /* ECSPI1 */ 116 fsl,spi-num-chipselects = <2>; 117 cs-gpios = <&gpio4 24 0>, /* GPIO4_24 */ 118 <&gpio4 25 0>; /* GPIO4_25 */ 119 status = "okay"; 120 121 pmic: mc13892@0 { 122 #address-cells = <1>; 123 #size-cells = <0>; 124 compatible = "fsl,mc13892"; 125 spi-max-frequency = <6000000>; 126 reg = <0>; 127 interrupt-parent = <&gpio0>; 128 interrupts = <8>; 129 130 leds { 131 #address-cells = <1>; 132 #size-cells = <0>; 133 led-control = <0x000 0x000 0x0e0 0x000>; 134 135 sysled { 136 reg = <3>; 137 label = "system:red:live"; 138 linux,default-trigger = "heartbeat"; 139 }; 140 }; 141 142 regulators { 143 sw1_reg: mc13892__sw1 { 144 regulator-min-microvolt = <600000>; 145 regulator-max-microvolt = <1375000>; 146 regulator-boot-on; 147 regulator-always-on; 148 }; 149 150 sw2_reg: mc13892__sw2 { 151 regulator-min-microvolt = <900000>; 152 regulator-max-microvolt = <1850000>; 153 regulator-boot-on; 154 regulator-always-on; 155 }; 156 }; 157 }; 158}; 159
