Tool/software: Linux
Hi, all:
I am working on bringing up ADC0 on the AM4379 in SDK ti-processor-sdk-linux-rt-am437x-evm-03.01.00.06, the hardware used ADC0_AIN7(XP)，ADC0_AIN6(XN)，ADC0_AIN5(YP)，ADC0_AIN4(YN) for the touchscreen wires, so I configure the DTS as following:
tscadc: tscadc@44e0d000 {
compatible = "ti,am3359-tscadc";
reg = <0x44e0d000 0x1000>;
ti,hwmods = "adc_tsc";
interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&adc_tsc_fck>;
clock-names = "fck";
status = "disabled";
tsc {
compatible = "ti,am3359-tsc";
};
adc {
#io-channel-cells = <1>;
compatible = "ti,am3359-adc";
};
};
&tscadc {
status = "okay";
tsc {
ti,wires = <4>;
ti,x-plate-resistance = <200>;
ti,coordinate-readouts = <5>;
ti,wire-config = <0x43 0x52 0x61 0x70>;
ti,charge-delay = <400>;
};
adc {
ti,adc-channels = <0 1 2 3>;
};
};
The problem is that when I touch the screen, the interrupt of ti_am335x_tsc can not trigger, I cat the directory "/sys/class/input/event0/devices/name" in my file system, I get "ti_tsc",
I don't know what problem, Can you help me? Thank you.
