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
|
||
|
|
