devicetree and libgpiod with gpio-line-names - Issue
I was wrongly relying on this link: http://next.patchew.org/Linux/[email protected]/mbox to resolve the issue. Using the implementation that revolved around the 3D word that can be seen in such a link.
From the moment I based on the 3 links below, I resolved the issue.
Just include in the imx7d-pico.dtsi file the items from &gpio1 - &gpio7. And in &gpio6, include "LED" in the fourteenth line.
