From 954f07012794a3aa7ae89e56f070eaa1643af50b Mon Sep 17 00:00:00 2001 From: Diederik de Haas Date: Fri, 11 Jul 2025 16:20:37 +0200 Subject: [PATCH] arm64: dts: rockchip: Add reset button to NanoPi R5S The NanoPi R5S LTS version has a reset button, which is connected via GPIO. Note that the non-LTS version does not have the reset button and therefore on page 19 of the schematic version 2204 it is marked 'NC', but it is connected on the LTS version.
