1 | * palmas regulator IP block devicetree bindings |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible : Should be from the list | |
| 5 | ti,twl6035-pmic | |
| 6 | ti,twl6036-pmic | |
| 7 | ti,twl6037-pmic | |
| 8 | ti,tps65913-pmic | |
| 9 | ti,tps65914-pmic | |
| 9b9fb420 | 10 | ti,tps65917-pmic |
| 8d561b60 K |
11 | and also the generic series names |
| 12 | ti,palmas-pmic | |
| 13 | - interrupt-parent : The parent interrupt controller which is palmas. | |
| 14 | - interrupts : The interrupt number and the type which can be looked up here: | |
| 15 | arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h | |
| 16 | - interrupts-name: The names of the individual interrupts. | |
| 17 | ||
| 18 | Optional properties: | |
| 19 | - ti,ldo6-vibrator : ldo6 is in vibrator mode | |
| 20 | ||
| 21 | Optional nodes: | |
| 22 | - regulators : Must contain a sub-node per regulator from the list below. | |
| 23 | Each sub-node should contain the constraints and initialization | |
| 24 | information for that regulator. See regulator.txt for a | |
| 25 | description of standard properties for these sub-nodes. | |
| 26 | Additional custom properties are listed below. | |
| 27 | ||
| 28 | For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP, | |
| 0416ea13 | 29 | smps45, smps457, smps7 depending on variant, smps6, smps[8-9], |
| 32b6d3f6 | 30 | smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb. |
| 8d561b60 K |
31 | |
| 32 | Optional sub-node properties: | |
| 33 | ti,warm-reset - maintain voltage during warm reset(boolean) | |
| 32b6d3f6 LD |
34 | ti,roof-floor - This takes as optional argument on platform supporting |
| 35 | the rail from desired external control. If there is no argument then | |
| 36 | it will be assume that it is controlled by NSLEEP pin. | |
| 37 | The valid value for external pins are: | |
| 38 | ENABLE1 then 1, | |
| 39 | ENABLE2 then 2 or | |
| 40 | NSLEEP then 3. | |
| 393536f8 | 41 | ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto, |
| 8d561b60 | 42 | 2 - eco, 3 - forced pwm |
| 8d561b60 K |
43 | ti,smps-range - OTP has the wrong range set for the hardware so override |
| 44 | 0 - low range, 1 - high range. | |
| 45 | ||
| b81eec09 BH |
46 | - ti,system-power-controller: Telling whether or not this pmic is controlling |
| 47 | the system power. | |
| 48 | ||
| 8d561b60 K |
49 | Example: |
| 50 | ||
| 51 | #include <dt-bindings/interrupt-controller/irq.h> | |
