1 NXP LPC18xx/43xx GPIO controller Device Tree Bindings
2 -----------------------------------------------------
5 - compatible : Should be "nxp,lpc1850-gpio"
6 - reg : List of addresses and lengths of the GPIO controller
8 - reg-names : Should be "gpio", "gpio-pin-ic", "gpio-group0-ic" and
9 "gpio-gpoup1-ic"
10 - clocks : Phandle and clock specifier pair for GPIO controller
11 - resets : Phandle and reset specifier pair for GPIO controller
12 - gpio-controller : Marks the device node as a GPIO controller
13 - #gpio-cells : Should be two:
14 - The first cell is the GPIO line number
15 - The second cell is used to specify polarity
16 - interrupt-controller : Marks the device node as an interrupt controller
17 - #interrupt-cells : Should be two:
18 - The first cell is an interrupt number within
19 0..9 range, for GPIO pin interrupts it is equal
20 to 'nxp,gpio-pin-interrupt' property value of
21 GPIO pin configuration, 8 is for GPIO GROUP0
22 interrupt, 9 is for GPIO GROUP1 interrupt
23 - The second cell is used to specify interrupt type
26 - gpio-ranges : Mapping between GPIO and pinctrl
