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
25Not all pins support all properties so either refer to the NXP 1850/4350
26user manual or the pin table in the pinctrl-lpc18xx driver for supported
27pin properties.

29Example:
30pinctrl: 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	};
57};
