The MiQi board's green LED doesn't work at all with the mainline kernel.
There are multiple reasons to this. First, the gpio number is wrong, it
is declared on gpio220 (chip 7 pin 4) instead of gpio218 (chip 7 pin 2).
Second, a pinctrl is referenced, also declared with the same wrong value
while it is not unused. Third, the GPIO polarity was wrong (active low
instead of active high) with the default value set to "default-on",
resulting in the LED being turned off even when the GPIO is correct.
This patch fixes all these inconsistencies at once since these they are
related to each other, and also restores the "timer" trigger which is
the same as the one used by the kernels shipped with the board.
It's important to note that during the port to mainline, the led's label
was changed from "System" to "miqi:green:user", so scripts making use of
the name will still not work until they're fixed.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
