From 2a7318b2586684e842f58cb7eeada2d8cb5d8151 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 26 May 2023 12:17:27 +0100 Subject: [PATCH] arm64: tegra: Fix PCIe regulator for Orin Jetson AGX The PCIe slot on the Jetson Orin AGX is not working and PCIe cards are not detected. The regulator for the 3.3V regulator for the PCIe is using the wrong GPIO for turning on the regulator. Fix this by updating the 3.3V regulator to use the correct GPIO.
