There are several ADC drivers that depend on the same device tree
bindings. Rather than continue to duplicate the properties, this patch
adds a common adc binding document that can be referenced. For beginning,
only two properties are documented.

Keeping it on the stack could cause an undefined behavior.

as measured by the digital lock detect circuitry. The mute to lock

- fixed indentation issues.
- used gpios instead of gpio.
- added vendor prefix for conversion-start-gpios, first-data-gpios,
and range-gpios.
Changes in v3

- Added SPDX-License-Identifier.
- Ordered the includes alphabetically.
- Used a threaded interrupt.
- Replaced
There are several ADC drivers that depend on the same device tree
bindings. Rather than continue to duplicate the properties, this patch
adds a common adc binding document that can be referenced. For beginning,
only two properties are documented.

There is no point in having three menu entries that can be selected
individually. Instead, the SPI and parallel interfaces should select
AD7606.

of the BUSY
signal triggers the interrupt.
ad7606_trigger_handler() is used as bottom half of the poll function.
It reads data from the device and stores it in the internal buffer.

When looking for the available scale or oversampling ratio, it is better
to use the find_closest() macro. This simplifies the code and also does
not require an exact value to be entered from the user space.

This patch replaces the use of wait_event_interruptible() with
wait_for_completion_timeout() when reading the result of a single
conversion. In this way, if the interrupt never occurs, the program will
not remain blocked.

The driver does not have a struct of_device_id table, but supported
devices are registered via Device Trees. This patch adds and OF device
ID table.

The 'adi' vendor prefix needs to be added to conversion-start, range,

Switch to devm version of request_irq, iio_triggered_buffer_setup,
iio_device_register. To avoid potential ordering issues in probe,
devm_add_action_or_reset() is used for the regulator_disable(). This
simplifies the code and decreases the chance of bugs.
