dev/roliver/ai_camera_gpio_acquire_release
When the imx500 driver is used as part of the 'AI Camera', the poweroff state is never reached as the camera and gpio driver share a regulator. By releasing the GPIOs when they are not in use, 'AI Camera' is able to achieve a powered-down state. Signed-off-by: Richard Oliver <richard.oliver@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.
