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) 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-str	- (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

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};
