··· 1 - AXP family PMIC device tree bindings 2 - 3 - The axp20x family current members : 4 - axp152 (X-Powers) 5 - axp202 (X-Powers) 6 - axp209 (X-Powers) 7 - axp221 (X-Powers) 8 - axp223 (X-Powers) 9 - axp803 (X-Powers) 10 - axp806 (X-Powers) 11 - axp809 (X-Powers) 12 - axp813 (X-Powers) 13 - 14 - The AXP813 is 2 chips packaged into 1. The 2 chips do not share anything 15 - other than the packaging. Pins are routed separately. As such they should 16 - be treated as separate entities. The other half is an AC100 RTC/codec 17 - combo chip. Please see ./ac100.txt for its bindings. 18 - 19 - Required properties: 20 - - compatible: should be one of: 21 - * "x-powers,axp152" 22 - * "x-powers,axp202" 23 - * "x-powers,axp209" 24 - * "x-powers,axp221" 25 - * "x-powers,axp223" 26 - * "x-powers,axp803" 27 - * "x-powers,axp806" 28 - * "x-powers,axp805", "x-powers,axp806" 29 - * "x-powers,axp305", "x-powers,axp805", "x-powers,axp806" 30 - * "x-powers,axp809" 31 - * "x-powers,axp813" 32 - - reg: The I2C slave address or RSB hardware address for the AXP chip 33 - - interrupt-controller: The PMIC has its own internal IRQs 34 - - #interrupt-cells: Should be set to 1 35 - 36 - Supported common regulator properties, see ../regulator/regulator.txt for 37 - more information: 38 - - regulator-ramp-delay: sets the ramp up delay in uV/us 39 - AXP20x/DCDC2: 1600, 800 40 - AXP20x/LDO3: 1600, 800 41 - - regulator-soft-start: enable the output at the lowest possible voltage and 42 - only then set the desired voltage 43 - AXP20x/LDO3: software-based implementation 44 - 45 - Optional properties: 46 - - interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin 47 - - x-powers,dcdc-freq: defines the work frequency of DC-DC in KHz 48 - AXP152/20X: range: 750-1875, Default: 1.5 MHz 49 - AXP22X/8XX: range: 1800-4050, Default: 3 MHz 50 - 51 - - x-powers,drive-vbus-en: boolean, set this when the N_VBUSEN pin is 52 - used as an output pin to control an external 53 - regulator to drive the OTG VBus, rather then 54 - as an input pin which signals whether the 55 - board is driving OTG VBus or not. 56 - (axp221 / axp223 / axp803/ axp813 only) 57 - 58 - - x-powers,self-working-mode and 59 - x-powers,master-mode: Boolean (axp806 only). Set either of these when the 60 - PMIC is wired for self-working mode or master mode. 61 - If neither is set then slave mode is assumed. 62 - This corresponds to how the MODESET pin is wired. 63 - 64 - - <input>-supply: a phandle to the regulator supply node. May be omitted if 65 - inputs are unregulated, such as using the IPSOUT output 66 - from the PMIC. 67 - 68 - - regulators: A node that houses a sub-node for each regulator. Regulators 69 - not used but preferred to be managed by the OS should be 70 - listed as well. 71 - See Documentation/devicetree/bindings/regulator/regulator.txt 72 - for more information on standard regulator bindings. 73 - 74 - Optional properties for DCDC regulators: 75 - - x-powers,dcdc-workmode: 1 for PWM mode, 0 for AUTO (PWM/PFM) mode 76 - Default: Current hardware setting 77 - The DCDC regulators work in a mixed PWM/PFM mode, 78 - using PFM under light loads and switching to PWM 79 - for heavier loads. Forcing PWM mode trades efficiency 80 - under light loads for lower output noise. This 81 - probably makes sense for HiFi audio related 82 - applications that aren't battery constrained. 83 - 84 - AXP202/AXP209 regulators, type, and corresponding input supply names: 85 - 86 - Regulator Type Supply Name Notes 87 - --------- ---- ----------- ----- 88 - DCDC2 : DC-DC buck : vin2-supply 89 - DCDC3 : DC-DC buck : vin3-supply 90 - LDO1 : LDO : acin-supply : always on 91 - LDO2 : LDO : ldo24in-supply : shared supply 92 - LDO3 : LDO : ldo3in-supply 93 - LDO4 : LDO : ldo24in-supply : shared supply 94 - LDO5 : LDO : ldo5in-supply 95 - 96 - AXP221/AXP223 regulators, type, and corresponding input supply names: 97 - 98 - Regulator Type Supply Name Notes 99 - --------- ---- ----------- ----- 100 - DCDC1 : DC-DC buck : vin1-supply 101 - DCDC2 : DC-DC buck : vin2-supply 102 - DCDC3 : DC-DC buck : vin3-supply 103 - DCDC4 : DC-DC buck : vin4-supply 104 - DCDC5 : DC-DC buck : vin5-supply 105 - DC1SW : On/Off Switch : : DCDC1 secondary output 106 - DC5LDO : LDO : : input from DCDC5 107 - ALDO1 : LDO : aldoin-supply : shared supply 108 - ALDO2 : LDO : aldoin-supply : shared supply 109 - ALDO3 : LDO : aldoin-supply : shared supply 110 - DLDO1 : LDO : dldoin-supply : shared supply 111 - DLDO2 : LDO : dldoin-supply : shared supply 112 - DLDO3 : LDO : dldoin-supply : shared supply 113 - DLDO4 : LDO : dldoin-supply : shared supply 114 - ELDO1 : LDO : eldoin-supply : shared supply 115 - ELDO2 : LDO : eldoin-supply : shared supply 116 - ELDO3 : LDO : eldoin-supply : shared supply 117 - LDO_IO0 : LDO : ips-supply : GPIO 0 118 - LDO_IO1 : LDO : ips-supply : GPIO 1 119 - RTC_LDO : LDO : ips-supply : always on 120 - DRIVEVBUS : Enable output : drivevbus-supply : external regulator 121 - 122 - AXP803 regulators, type, and corresponding input supply names: 123 - 124 - Regulator Type Supply Name Notes 125 - --------- ---- ----------- ----- 126 - DCDC1 : DC-DC buck : vin1-supply 127 - DCDC2 : DC-DC buck : vin2-supply : poly-phase capable 128 - DCDC3 : DC-DC buck : vin3-supply : poly-phase capable 129 - DCDC4 : DC-DC buck : vin4-supply 130 - DCDC5 : DC-DC buck : vin5-supply : poly-phase capable 131 - DCDC6 : DC-DC buck : vin6-supply : poly-phase capable 132 - DC1SW : On/Off Switch : : DCDC1 secondary output 133 - ALDO1 : LDO : aldoin-supply : shared supply 134 - ALDO2 : LDO : aldoin-supply : shared supply 135 - ALDO3 : LDO : aldoin-supply : shared supply 136 - DLDO1 : LDO : dldoin-supply : shared supply 137 - DLDO2 : LDO : dldoin-supply : shared supply 138 - DLDO3 : LDO : dldoin-supply : shared supply 139 - DLDO4 : LDO : dldoin-supply : shared supply 140 - ELDO1 : LDO : eldoin-supply : shared supply 141 - ELDO2 : LDO : eldoin-supply : shared supply 142 - ELDO3 : LDO : eldoin-supply : shared supply 143 - FLDO1 : LDO : fldoin-supply : shared supply 144 - FLDO2 : LDO : fldoin-supply : shared supply 145 - LDO_IO0 : LDO : ips-supply : GPIO 0 146 - LDO_IO1 : LDO : ips-supply : GPIO 1 147 - RTC_LDO : LDO : ips-supply : always on 148 - DRIVEVBUS : Enable output : drivevbus-supply : external regulator 149 - 150 - AXP806 regulators, type, and corresponding input supply names: 151 - 152 - Regulator Type Supply Name Notes 153 - --------- ---- ----------- ----- 154 - DCDCA : DC-DC buck : vina-supply : poly-phase capable 155 - DCDCB : DC-DC buck : vinb-supply : poly-phase capable 156 - DCDCC : DC-DC buck : vinc-supply : poly-phase capable 157 - DCDCD : DC-DC buck : vind-supply : poly-phase capable 158 - DCDCE : DC-DC buck : vine-supply : poly-phase capable 159 - ALDO1 : LDO : aldoin-supply : shared supply 160 - ALDO2 : LDO : aldoin-supply : shared supply 161 - ALDO3 : LDO : aldoin-supply : shared supply 162 - BLDO1 : LDO : bldoin-supply : shared supply 163 - BLDO2 : LDO : bldoin-supply : shared supply 164 - BLDO3 : LDO : bldoin-supply : shared supply 165 - BLDO4 : LDO : bldoin-supply : shared supply 166 - CLDO1 : LDO : cldoin-supply : shared supply 167 - CLDO2 : LDO : cldoin-supply : shared supply 168 - CLDO3 : LDO : cldoin-supply : shared supply 169 - SW : On/Off Switch : swin-supply 170 - 171 - Additionally, the AXP806 DC-DC regulators support poly-phase arrangements 172 - for higher output current.

This probably makes sense for HiFi audio related 284 + applications that aren't battery constrained. 285 + 286 + additionalProperties: false 287 + 288 + required: 289 + - compatible 290 + - reg 291 + - "#interrupt-cells" 292 + - interrupt-controller 293 + 294 + additionalProperties: false 295 + 296 + examples: 297 + - | 298 + i2c0 { 299 + #address-cells = <1>; 300 + #size-cells = <0>; 301 + 302 + pmic@30 { 303 + compatible = "x-powers,axp152"; 304 + reg = <0x30>; 305 + interrupts = <0>; 306 + interrupt-controller; 307 + #interrupt-cells = <1>; 308 + }; 309 + }; 310 + 311 + - | 312 + #include <dt-bindings/interrupt-controller/irq.h> 313 + 314 + i2c0 { 315 + #address-cells = <1>; 316 + #size-cells = <0>; 317 + 318 + pmic@34 { 319 + compatible = "x-powers,axp209"; 320 + reg = <0x34>; 321 + interrupt-parent = <&nmi_intc>; 322 + interrupts = <0 IRQ_TYPE_LEVEL_LOW>; 323 + interrupt-controller; 324 + #interrupt-cells = <1>; 325 + 326 + ac_power_supply: ac-power { 327 + compatible = "x-powers,axp202-ac-power-supply"; 328 + }; 329 + 330 + axp_adc: adc { 331 + compatible = "x-powers,axp209-adc"; 332 + #io-channel-cells = <1>; 333 + }; 334 + 335 + axp_gpio: gpio { 336 + compatible = "x-powers,axp209-gpio"; 337 + gpio-controller; 338 + #gpio-cells = <2>; 339 + 340 + gpio0-adc-pin { 341 + pins = "GPIO0"; 342 + function = "adc"; 343 + }; 344 + }; 345 + 346 + battery_power_supply: battery-power { 347 + compatible = "x-powers,axp209-battery-power-supply"; 348 + }; 349 + 350 + regulators { 351 + /* Default work frequency for buck regulators */ 352 + x-powers,dcdc-freq = <1500>; 353 + 354 + reg_dcdc2: dcdc2 { 355 + regulator-always-on; 356 + regulator-min-microvolt = <1000000>; 357 + regulator-max-microvolt = <1450000>; 358 + regulator-name = "vdd-cpu"; 359 + }; 360 + 361 + reg_dcdc3: dcdc3 { 362 + regulator-always-on; 363 + regulator-min-microvolt = <1000000>; 364 + regulator-max-microvolt = <1400000>; 365 + regulator-name = "vdd-int-dll"; 366 + }; 367 + 368 + reg_ldo1: ldo1 { 369 + /* LDO1 is a fixed output regulator */ 370 + regulator-always-on; 371 + regulator-min-microvolt = <1300000>; 372 + regulator-max-microvolt = <1300000>; 373 + regulator-name = "vdd-rtc"; 374 + }; 375 + 376 + reg_ldo2: ldo2 { 377 + regulator-always-on; 378 + regulator-min-microvolt = <3000000>; 379 + regulator-max-microvolt = <3000000>; 380 + regulator-name = "avcc"; 381 + }; 382 + 383 + reg_ldo3: ldo3 { 384 + regulator-name = "ldo3"; 385 + }; 386 + 387 + reg_ldo4: ldo4 { 388 + regulator-name = "ldo4"; 389 + }; 390 + 391 + reg_ldo5: ldo5 { 392 + regulator-name = "ldo5"; 393 + }; 394 + }; 395 + 396 + usb_power_supply: usb-power { 397 + compatible = "x-powers,axp202-usb-power-supply"; 398 + }; 399 + }; 400 + };
