1Intel x86 PINCTRL/GPIO controller 2 3Pin-muxing on x86 can be described with a node for the PINCTRL master 4node and a set of child nodes for each pin on the SoC. 5 6The PINCTRL master node requires the following properties: 7- compatible : "intel,x86-pinctrl" 8 9Pin nodes must be children of the pinctrl master node and can 10contain the following properties: 11- pad-offset - (required) offset in the IOBASE for the pin to configure 12- gpio-offset - (required only when 'mode-gpio' is set) 2 cells 13 - offset in the GPIOBASE for the pin to configure 14 - the bit shift in this register (4 = bit 4) 15- mode-gpio - (optional) standalone property to force the pin into GPIO mode 16- mode-func - (optional) function number to assign to the pin. If 17 'mode-gpio' is set, this property will be ignored. 18in case of 'mode-gpio' property set: 19- output-value - (optional) this set the default output value of the GPIO 20- direction - (optional) this set the direction of the gpio 21- pull-strength - (optional) this set the pull strength of the pin 22- pull-assign - (optional) this set the pull assignement (up/down) of the pin 23- invert - (optional) this input pin is inverted 24 25Example: 26 27pin_usb_host_en0@0 { 28 gpio-offset = <0x80 8>; 29 pad-offset = <0x260>; 30 mode-gpio; 31 output-value = <1>; 32 direction = <PIN_OUTPUT>; 33}; 34
