It's capable of booting up into the serial console. Signed-off-by: Xianwei Zhao --- V3 -> V4: cleaned up coding style. V2 -> V3: add of dts board compatible family. V1 -> V2: cleaned up coding style, modify CPU affinity of timer interrups, and modify GIC reg defintions. --- arch/arm64/boot/dts/amlogic/Makefile | 1 + .../dts/amlogic/meson-s4-s805x2-aq222.dts | 30 ++++++ arch/arm64/boot/dts/amlogic/meson-s4.dtsi | 99 +++++++++++++++++++ 3 files changed, 130 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-s4-s805x2-aq222.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-s4.dtsi base-commit: c5468e3c930d4d2937d3a842a85df0f74e95e152 diff --git a/arch/arm64/boot/dts/amlogic/Makefile b/arch/arm64/boot/dts/amlogic/Makefile index 5148cd9e5146..faea74a45994 100644 --- a/arch/arm64/boot/dts/amlogic/Makefile +++ b/arch/arm64/boot/dts/amlogic/Makefile @@ -57,3 +57,4 @@ dtb-$(CONFIG_ARCH_MESON) += meson-sm1-odroid-c4.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-odroid-hc4.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-sei610.dtb dtb-$(CONFIG_ARCH_MESON) += meson-a1-ad401.dtb +dtb-$(CONFIG_ARCH_MESON) += meson-s4-s805x2-aq222.dtb diff --git a/arch/arm64/boot/dts/amlogic/meson-s4-s805x2-aq222.dts b/arch/arm64/boot/dts/amlogic/meson-s4-s805x2-aq222.dts new file mode 100644 index 000000000000..a942d7e06d6e --- /dev/null +++ b/arch/arm64/boot/dts/amlogic/meson-s4-s805x2-aq222.dts @@ -0,0 +1,30 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2021 Amlogic, Inc.
