From 1b5bad01abdcefd1bbf58590d5a78e15741f6a34 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 7 Dec 2021 11:03:12 +0100 Subject: ARM: tegra: Rename GPU node on Tegra124 In order to be able to pass DT schema validation, change the GPU nodes' unit-address to the standard notation. Previously this was using a "0," prefix that originated from a time when the top-level device tree node contained #address-cells = <2>. Note that this technically breaks backwards-compatibility with certain older versions of the U-Boot bootloader because early versions used a hard-coded DT path lookup to find the GPU node and perform some fixups on it. However, this was changed to a compatible string based lookup in April 2016, so it's reasonable to expect people to update U-Boot on the systems that they want to use this updated kernel DTB with.
