Currently, on Radxa boards, the power LED is turned on immediately after power-up, independent of software control. The heartbeat LED and other available LEDs are subsequently turned on by the initial software, such as U-Boot, to indicate software is running. However, the device tree description for this behavior is inconsistent and fragmented, with definitions split between the main Linux DTS files and separate U-Boot files (u-boot/arch/arm/dts/*-u-boot.dtsi). This patch addresses the inconsistency for the power LED by using default-state = "on" instead of linux,default-trigger = "default-on".

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.
