From d77f8443c7c07ac37b70f812ffa774b55bcef91c Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 7 May 2026 19:37:48 +0200 Subject: arm64: dts: renesas: Switch to upstream DT on Renesas R-Car X5H R8A78000 Enable OF_UPSTREAM to use upstream Linux kernel DT source as a base for U-Boot control DT. Retain currently present parts of the DT which are not yet part of upstream Linux kernel DT in -u-boot.dtsi files until they get replaced by upstream equivalents. Add renesas/ prefix to the DEFAULT_DEVICE_TREE as part of the switch. Unused i2c2..i2c8 nodes have been removed, and will become available once upstream Linux kernel DT adds those nodes. The DRAM_RSV_SIZE has been updated to cover first 518 MiB of DRAM, which are reserved for firmware and other use. Note that all DT parts in -u-boot.dtsi are not considered stable DT bindings and may change before they land in Linux kernel and become stable DT ABI.
