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. 28 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}; 58
