   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 Not all pins support all properties so either refer to the NXP 1850/4350
  26 user manual or the pin table in the pinctrl-lpc18xx driver for supported
  27 pin properties.

  29 Example:
  30 pinctrl: pinctrl@40086000 {
  31         compatible = "nxp,lpc1850-scu";
  32         reg = <0x40086000 0x1000>;
  33         clocks = <&ccu1 CLK_CPU_SCU>;
  34
  35         i2c0_pins: i2c0-pins {
  36                 i2c0_pins_cfg {
  37                         pins = "i2c0_scl", "i2c0_sda";
  38                         function = "i2c0";
  39                         input-enable;
  40                 };
  41         };
  42
  43         uart0_pins: uart0-pins {
  44                 uart0_rx_cfg {
  45                         pins = "pf_11";
  46                         function = "uart0";
  47                         bias-disable;
  48                         input-enable;
  49                 };
  50
  51                 uart0_tx_cfg {
  52                         pins = "pf_10";
  53                         function = "uart0";
  54                         bias-disable;
  55                 };
  56         };
