I am currently writing a device tree node to configure NXP SCI6IS752 Dual Channel UART with I2C which is connected to the slave address 0x4d. I am also using a clock of 1.8432MHz. The IRQ pin of SCISIS752 is attached to an IO Expander GPIO which is gpiopin 456 in my case. My dts configuration:
sc16is752@4d { compatible = "nxp,sc16is752"; reg = <0x4d>; clocks = <&sc16is752_clk>; interrupt-parent = <&gpio3>; interrupts = <7 2>; gpio-controller; #gpio-cells = <2>; sc16is752_clk: sc16is752_clk { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <1843200>; };};
How do I set the values of interrupt-parent and interrupts for this configuration?
