* MELFAS MIP4 Touchscreen
|
||||
|
||||
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>;
