Linux/AM3354: ADC

Part Number: AM3354

Tool/software: Linux

Hi,

Followed below link to configure adc channels,

http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide

board file has,

/* TSc controller */
static struct tsc_data am335x_touchscreen_data = {
.wires = 4,
.x_plate_resistance = 200,
.steps_to_configure = 5,
};

static struct adc_data am335x_adc_data = {
.adc_channels = 4,
};

static struct mfd_tscadc_board tscadc = {
.tsc_init = &am335x_touchscreen_data,
.adc_init = &am335x_adc_data,
};

and mfd_tscadc_init() is called.

After booting i am observing empty under path /sys/bus/iio/devices.

Note:-

Kernel : 3.2.0

Configured drivers as built-in.

Thanks and Regards

Dileep
