Uses the regulator notifier framework so that the current focus position will be restored whenever any user of the regulator powers it up. This means that should the VCM and sensor share a common regulator then starting the sensor will automatically restore the default position. If they have independent regulators then it will behave be powered up when the VCM subdev is opened. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
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 Restructured Text 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.
