From 5adbc0e5caa3b0f3ca1211c952e0822fde8e8e5b Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 20 Aug 2019 07:20:58 -0500 Subject: [PATCH] ARM: dts: logicpd-som-lv: Fix i2c2 and i2c3 Pin mux When the pinmux configuration was added, it was accidentally placed into the omap3_pmx_wkup node when it should have been placed into the omap3_pmx_core. This error was accidentally propagated to U-Boot by me when I blindly copied the device tree from Linux. This patch moves the i2c2_pins and i2c3_pins to the correct node which should eliminate i2c bus errors and timeouts due to the fact the bootloader uses the save device tree that no longer properly assigns these pins.
