Required properties:
- compatible: must be "melfas,mip4_ts"
- reg: I2C slave address of the chip (0x48 or 0x34)
- interrupt-parent: interrupt controller to which the chip is connected
- interrupts: interrupt to which the chip is connected
Optional properties:
- ce-gpios: GPIO connected to the CE (chip enable) pin of the chip
Example:
i2c@00000000 {
touchscreen: melfas_mip4@48 {
compatible = "melfas,mip4_ts";
reg = <0x48>;
interrupt-parent = <&gpio>;
interrupts = <0 IRQ_TYPE_EDGE_FALLING>;
ce-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
