| Imagis ISA1200 Haptics Vibrator |
| |
| Required properties: |
| - reg: slave address of bus |
| - compatible: should be "imagis,isa1200" |
| - label: name for vibrator directory |
| - imagis,hap-en-gpio: haptic enable gpio |
| - imagis,mode-ctrl: mode of the controller, 0 = POWER_DOWN_MODE, |
| 1 = PWM_INPUT_MODE, 2 = PWM_GEN_MODE, 3 = WAVE_GEN_MODE |
| - imagis,max-timeout: maximum timeout for vibration |
| - imagis,chip-en: chip enable |
| - vcc_i2c-supply: regulator supplying i2c bus |
| |
| Regulator described as a child of the main device: |
| - regulator-name: A string used as a descriptive name for regulator outputs, |
| should match vcc_i2c above |
| - regulator-min-microvolt: smallest voltage consumers may set |
| - regulator-max-microvolt: largest voltage consumers may set |
| - regulator-max-microamp: largest current consumers may set |
| |
| Optional properties: |
| - imagis,smart-en: automatically control haptic power based on pwm/clk signal |
| - imagis,is-erm: controlled by dc motor, use ERM driving method |
| - imagis,overdrive-high: overdrive high |
| - imagis,overdrive-en: enable overdrive |
| - imagis,pwm-freq: pwm frequency (hZ) |
| - imagis,pwm-ch-id: pwm channel id |
| - imagis,pwm-div: pwm division to be used for vibration |
| - imagis,need-pwm-clk: use "pwm_clk" |
| - imagis,hap-len-gpio: haptic ldo enable gpio |
| - imagis,etc-clk-en: use external clock |
| - xyz-supply: to be used if additional regulators are require beyond |
| "imagis,regulator" above |
| |
| Any additional regulators are described as child nodes of main device: |
| - regulator-name: A string used as a descriptive name for regulator outputs, |
| should match supply "xyz" |
| - regulator-min-microvolt: smallest voltage consumers may set |
| - regulator-max-microvolt: largest voltage consumers may set |
| - regulator-max-microamp: largest current consumers may set |
