Linux kernel source tree
d569ae0f05
The AD7768-1 has the ability to control other local hardware (such as gain stages),to power down other blocks in the signal chain, or read local status signals over the SPI interface. Add direct mode conditional locks in the GPIO callbacks to prevent register access when the device is in buffered mode. This change exports the AD7768-1's four GPIOs and makes them accessible at an upper layer.

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.
