From 87743e9bc150774a14516569287184597603c42d Mon Sep 17 00:00:00 2001 From: Justin Lewis Date: Sun, 26 Oct 2025 16:54:05 -0700 Subject: [PATCH] Add support for Jetson Orin Nano Super variant Add support for Jetson Orin Nano "Super" developer kit variants that include the "-super" suffix in their device tree compatible string. The Super variants report compatible strings like: - nvidia,p3509-0000+p3767-0003-super - nvidia,p3509-0000+p3767-0004-super - nvidia,p3509-0000+p3767-0005-super This fix enables GPIO library functionality for these newer hardware variants by adding the Super-suffixed compatible strings to the device recognition lists.
