From 44e3f867fd3f75123b0e8e460f723a115b0d8cd4 Mon Sep 17 00:00:00 2001 From: Nick Xie Date: Thu, 15 Jan 2026 11:00:15 +0800 Subject: [PATCH] arm64: dts: meson-s4-s905y4-khadas-vim1s: add initial device tree The Khadas VIM1S uses the Amlogic S905Y4 SoC, based on the Amlogic S4 SoC family, on a board with the same form factor as the VIM/VIM2/VIM3/VIM4 models. Serial debug console, ethernet, SD card work with this initial device tree. It features: - 2GB LPDDR4 RAM - 16GB eMMC 5.1 storage - 32MB SPI flash - 100M Ethernet - AP6256 Wireless (802.11 a/b/g/n/ac, BT5.0) - HDMI 2.1 video - 2x USB 2.0 ports - 1x USB-C (power) with USB 2.0 OTG - 2x LED's (1x red, 1x white) - 3x buttons (power, function, reset) - IR receiver - 40pin GPIO Header - 1x micro SD card slot Signed-off-by: Nick Xie Reviewed-by: Neil Armstrong Link: https://patch.msgid.link/20260115030015.1334517-4-nick@khadas.com Signed-off-by: Neil Armstrong --- arch/arm64/boot/dts/amlogic/Makefile | 1 + .../amlogic/meson-s4-s905y4-khadas-vim1s.dts | 190 ++++++++++++++++++ 2 files changed, 191 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-s4-s905y4-khadas-vim1s.dts diff --git a/arch/arm64/boot/dts/amlogic/Makefile b/arch/arm64/boot/dts/amlogic/Makefile index 219fb088c704d..15f9c817e5023 100644 --- a/arch/arm64/boot/dts/amlogic/Makefile +++ b/arch/arm64/boot/dts/amlogic/Makefile @@ -85,6 +85,7 @@ dtb-$(CONFIG_ARCH_MESON) += meson-gxm-ugoos-am3.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-vega-s96.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-wetek-core2.dtb dtb-$(CONFIG_ARCH_MESON) += meson-s4-s805x2-aq222.dtb +dtb-$(CONFIG_ARCH_MESON) += meson-s4-s905y4-khadas-vim1s.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-a95xf3-air-gbit.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-a95xf3-air.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-bananapi-m2-pro.dtb diff --git a/arch/arm64/boot/dts/amlogic/meson-s4-s905y4-khadas-vim1s.dts b/arch/arm64/boot/dts/amlogic/meson-s4-s905y4-khadas-vim1s.dts new file mode 100644 index 0000000000000..79ffc703a2e99 --- /dev/null +++ b/arch/arm64/boot/dts/amlogic/meson-s4-s905y4-khadas-vim1s.dts @@ -0,0 +1,190 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2026 Khadas Technology Co., Ltd. + */ + +/dts-v1/;
