bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available
on all Raspberry Pi boards. But there is no driver for this particual
GPIO on CM3 in mainline yet, so this node was left incomplete without
the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return
value mismatch of function gpiod_get_from_of_node()") this causing probe
issues of the leds-gpio driver for users of the CM3 dtsi file.
leds-gpio: probe of leds failed with error -2
Until we have the necessary GPIO driver hide the ACT node for CM3
to avoid this.

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.
