From ba9858c53a797c018a1bbc93776e7baf3ec35ebf Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 26 Jul 2023 18:30:08 +0200 Subject: [PATCH] ARM: tegra: Reuse I2C3 for NVEC Instead of duplicating the I2C3 node and adding NVEC specific properties, reuse the I2C3 node, extend it with NVEC specific properties and drop properties that are not needed by NVEC. This results in a DTB that is a bit cleaner and avoids accidentally using I2C3 and NVEC which would have them fight over the same hardware resources.
