1NXP LPC18xx/43xx SCU pin controller Device Tree Bindings
2--------------------------------------------------------
3
4Required 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
9The lpc1850-scu driver uses the generic pin multiplexing and generic pin
10configuration documented in pinctrl-bindings.txt.
11
12The 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
25NXP specific properties:
26 - nxp,gpio-pin-interrupt : Assign pin to gpio pin interrupt controller
27			    irq number 0 to 7. See example below.
28
29Not all pins support all properties so either refer to the NXP 1850/4350
30user manual or the pin table in the pinctrl-lpc18xx driver for supported
31pin properties.

33Example:
34pinctrl: pinctrl@40086000 {
35	compatible = "nxp,lpc1850-scu";
36	reg = <0x40086000 0x1000>;
37	clocks = <&ccu1 CLK_CPU_SCU>;
38
39	i2c0_pins: i2c0-pins {
40		i2c0_pins_cfg {
41			pins = "i2c0_scl", "i2c0_sda";
42			function = "i2c0";
43			input-enable;
44		};
45	};
46
47	uart0_pins: uart0-pins {
48		uart0_rx_cfg {
49			pins = "pf_11";
50			function = "uart0";
51			bias-disable;
52			input-enable;
53		};
54
55		uart0_tx_cfg {
56			pins = "pf_10";
57			function = "uart0";
58			bias-disable;
59		};
60	};
61
62	gpio_joystick_pins: gpio-joystick-pins {
63		gpio_joystick_1_cfg {
64			pins =  "p9_0";
65			function = "gpio";
66			nxp,gpio-pin-interrupt = <0>;
67			input-enable;
68			bias-disable;
69		};
70	};
