1Texas Instruments TWL family (twl4030) reset and power management module 2 3The power management module inside the TWL family provides several facilities 4to control the power resources, including power scripts. For now, the 5binding only supports the complete shutdown of the system after poweroff. 6 7Required properties: 8- compatible : must be one of the following 9 "ti,twl4030-power" 10 "ti,twl4030-power-reset" 11 "ti,twl4030-power-idle" 12 "ti,twl4030-power-idle-osc-off" 13 14The use of ti,twl4030-power-reset is recommended at least on 153530 that needs a special configuration for warm reset to work. 16 17When using ti,twl4030-power-idle, the TI recommended configuration 18for idle modes is loaded to the tlw4030 PMIC. 19 20When using ti,twl4030-power-idle-osc-off, the TI recommended 21configuration is used with the external oscillator being shut 22down during off-idle. Note that this does not work on all boards 23depending on how the external oscillator is wired. 24 25Optional properties: 26- ti,use_poweroff: With this flag, the chip will initiates an ACTIVE-to-OFF or 27 SLEEP-to-OFF transition when the system poweroffs. 28 29Example: 30&i2c1 { 31 clock-frequency = <2600000>; 32 33 twl: twl@48 { 34 reg = <0x48>; 35 interrupts = <7>; /* SYS_NIRQ cascaded to intc */ 36 interrupt-parent = <&intc>; 37 38 twl_power: power { 39 compatible = "ti,twl4030-power"; 40 ti,use_poweroff; 41 }; 42 }; 43}; 44
