From 5e4bbe52207c3927dd2690e46bdbef6392d7bde4 Mon Sep 17 00:00:00 2001 From: Vedant Deshpande Date: Thu, 27 Jun 2024 21:53:16 +0000 Subject: [PATCH] arm64: tegra: Restructure Orin NX/Nano device tree The Orin NX and Orin Nano boards share a common carrier board and the module boards for both platforms are very similar. Therefore, restructure the Orin NX/Nano device-tree source files to adhere to a simple hierarchical format. This will help make clear where changes should go, and eliminates redundancy within the files. Previously the carrier board file was independent. However, given that it is so tightly coupled with the module design, it will be more practical to combine files together for a simpler layout. Following changes are made to restructure the device tree source files: 1) Change include hierarchy. Top-level dts includes board dtsi. Board dtsi includes module dtsi. Module dtsi includes SoC dtsi. 2) Data from the top level dts file that is common to both Orin NX and Orin Nano is in tegra234-p3768-0000+p3767.dtsi. 3) Only data that is unique to NX/Nano is present in the top-level dts.
