Assign a label to latch1 GPIO device the LEDs hang off, enumerate its pins for the purpose of indexing gpio_led table, remove hardcoded GPIO numbers from that table replacing them with invalid GPIO numbers and remove initialization of incompletely described LED device from machine_init. As soon as the latch1 GPIO device is registered, use its label to find respective GPIO chip, identify each LED's GPIO descriptor by its pin number and assign its gobal GPIO number to the gpio_led table. Once completed, register the LED device. Created and tested against linux-v4.17-rc3. Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
