    1 NXP LPC18xx/43xx SCU pin controller Device Tree Bindings
    2 --------------------------------------------------------
    3 
    4 Required properties:
    5 - compatible            : Should be "nxp,lpc1850-scu"
    6 - reg                   : Address and length of the register set for the device
    7 - clocks                : Clock specifier (see clock bindings for details)
    8 
    9 The lpc1850-scu driver uses the generic pin multiplexing and generic pin
   10 configuration documented in pinctrl-bindings.txt.
   11 
   12 The following generic nodes are supported:
   13  - function
   14  - pins
   15  - bias-disable
   16  - bias-pull-up
   17  - bias-pull-down
   18  - drive-strength
   19  - input-enable
   20  - input-disable
   21  - input-schmitt-enable
   22  - input-schmitt-disable
   23  - slew-rate
   24 
   25 NXP specific properties:
   26  - nxp,gpio-pin-interrupt : Assign pin to gpio pin interrupt controller
   27                             irq number 0 to 7. See example below.
   28 
   29 Not all pins support all properties so either refer to the NXP 1850/4350
   30 user manual or the pin table in the pinctrl-lpc18xx driver for supported
   31 pin properties.
   32 
   33 Example:
   34 pinctrl: pinctrl@40086000 {
   35         compatible = "nxp,lpc1850-scu";
   36         reg = <0x40086000 0x1000>;
   37         clocks = <&ccu1 CLK_CPU_SCU>;
