|
|||
|
||||
Pin nodes must be children of the pinctrl master node and can
|
||||
contain the following properties:
|
||||
- pad-offset - (required) offset in the IOBASE for the pin to configured.
|
||||
- gpio-offset - (required) offset in the GPIOBASE for the pin to configured and
|
||||
also the bit shift in this register.
|
||||
- mode-gpio - (optional) standalone property to force the pin into GPIO mode.
|
||||
- mode-func - (optional) function number to assign to the pin. if 'mode-gpio'
|
||||
is set, this property will be ignored.
|
||||
- pad-offset - (required) offset in the IOBASE for the pin to configure
|
||||
- gpio-offset - (required) 2 cells
|
||||
- offset in the GPIOBASE for the pin to configure
|
||||
- the bit shift in this register (4 = bit 4)
|
||||
- mode-gpio - (optional) standalone property to force the pin into GPIO mode
|
||||
- mode-func - (optional) function number to assign to the pin. If
|
||||
'mode-gpio' is set, this property will be ignored.
|
||||
in case of 'mode-gpio' property set:
|
||||
- output-value - (optional) this set the default output value of the GPIO.
|
||||
- direction - (optional) this set the direction of the gpio.
|
||||
- pull-str - (optional) this set the pull strength of the pin.
|
||||
- pull-assign - (optional) this set the pull assignement (up/down) of the pin.
|
||||
- output-value - (optional) this set the default output value of the GPIO
|
||||
- direction - (optional) this set the direction of the gpio
|
||||
- pull-str - (optional) this set the pull strength of the pin
|
||||
- pull-assign - (optional) this set the pull assignement (up/down) of the pin
|
||||
- invert - (optional) this input pin is inverted
