* NXP LPC32xx SoC ADC controller
Required properties:
- compatible: must be "nxp,lpc3220-adc"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: The ADC interrupt
Example:
adc@40048000 {
compatible = "nxp,lpc3220-adc";
reg = <0x40048000 0x1000>;
interrupt-parent = <&mic>;

Required properties:
- compatible: Should be "st,spear600-adc"
- reg: Address and length of the register set for the device
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupts: Should contain the ADC interrupt
- sampling-frequency: Default sampling frequency
Optional properties:
- vref-external: External voltage reference in milli-volts. If omitted
the internal voltage reference will be used.
- average-samples: Number of samples to generate an average value. If
omitted, single data conversion will be used.
Examples:
adc: adc@d8200000 {
compatible = "st,spear600-adc";
reg = <0xd8200000 0x1000>;
interrupt-parent = <&vic1>;

tristate "Industrial I/O support"
depends on GENERIC_HARDIRQS
help
The industrial I/O subsystem provides a unified framework for
drivers for many different types of embedded sensors using a
number of different physical interfaces (i2c, spi, etc). See
Documentation/iio for more information.

help
Provide core support for various buffer based data
acquisition methods.
if IIO_BUFFER
config IIO_KFIFO_BUF
select IIO_TRIGGER
tristate "Industrial I/O buffering based on kfifo"
help
A simple fifo based on kfifo. Use this if you want a fifo
rather than a ring buffer. Note that this currently provides
no buffer events so it is up to userspace to work out how
often to read from the buffer.
endif # IIO_BUFFER
config IIO_TRIGGER
boolean "Enable triggered sampling support"
help
Provides IIO core support for triggers. Currently these
are used to initialize capture of samples to push into
ring buffers. The triggers are effectively a 'capture
data now' interrupt.
config IIO_CONSUMERS_PER_TRIGGER
int "Maximum number of consumers per trigger"
depends on IIO_TRIGGER
default "2"
help
This value controls the maximum number of consumers that a
given trigger may handle. Default is 2.
