18c2ecf20Sopenharmony_ciTPS51632 Voltage regulators 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciRequired properties: 48c2ecf20Sopenharmony_ci- compatible: Must be "ti,tps51632" 58c2ecf20Sopenharmony_ci- reg: I2C slave address 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciOptional properties: 88c2ecf20Sopenharmony_ci- ti,enable-pwm-dvfs: Enable the DVFS voltage control through the PWM interface. 98c2ecf20Sopenharmony_ci- ti,dvfs-step-20mV: The 20mV step voltage when PWM DVFS enabled. Missing this 108c2ecf20Sopenharmony_ci will set 10mV step voltage in PWM DVFS mode. In normal mode, the voltage 118c2ecf20Sopenharmony_ci step is 10mV as per datasheet. 128c2ecf20Sopenharmony_ci 138c2ecf20Sopenharmony_ciAny property defined as part of the core regulator binding, defined in 148c2ecf20Sopenharmony_ciregulator.txt, can also be used. 158c2ecf20Sopenharmony_ci 168c2ecf20Sopenharmony_ciExample: 178c2ecf20Sopenharmony_ci 188c2ecf20Sopenharmony_ci tps51632 { 198c2ecf20Sopenharmony_ci compatible = "ti,tps51632"; 208c2ecf20Sopenharmony_ci reg = <0x43>; 218c2ecf20Sopenharmony_ci regulator-name = "tps51632-vout"; 228c2ecf20Sopenharmony_ci regulator-min-microvolt = <500000>; 238c2ecf20Sopenharmony_ci regulator-max-microvolt = <1500000>; 248c2ecf20Sopenharmony_ci regulator-boot-on; 258c2ecf20Sopenharmony_ci ti,enable-pwm-dvfs; 268c2ecf20Sopenharmony_ci ti,dvfs-step-20mV; 278c2ecf20Sopenharmony_ci }; 28
