The ROHM BD79105 is a simple, 16-bit, 1-channel ADC with a 'CONVSTART' pin used to start the ADC conversion. Other than the 'CONVSTART', there are 3 supply pins (one used as a reference), analog inputs, ground and communication pins. It's worth noting that the pin somewhat confusingly labeled as 'DIN', is a pin which should be used as a chip-select. The IC does not have any writable registers. The device is designed so that the output pin can, in addition to outputting the data, be used as a 'data-ready'-IRQ. There are cases where the IRQ can't be used (because it is delivered via SPI data-line). Hence, some systems may use a GPIO for polling the data readiness. Add a compatible for the bd79105 and add the data-ready GPIO to the binding.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
