Signed-off-by: Sam Shih --- v7: added memory node back to dts v6: removed clock and pinctrl node, to separate basic part into a single patch series Original thread: https://lore.kernel.org/all/20211004124155.1404-1-sam.shih@mediatek.com/ v5: follow reviewr's comment: removed clock freqency node in timer due to we have set CNTFRQ_EL0 in ATF firmware, and also corrected GICD range v4: added missing gic register bases, and fixed range of GICR v3: used the stdout-path instead of console=ttyS0 v2: modified clock and uart node due to clock driver updated --- arch/arm64/boot/dts/mediatek/Makefile | 1 + arch/arm64/boot/dts/mediatek/mt7986a-rfb.dts | 38 +++++ arch/arm64/boot/dts/mediatek/mt7986a.dtsi | 149 +++++++++++++++++++ 3 files changed, 188 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt7986a-rfb.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt7986a.dtsi diff --git a/arch/arm64/boot/dts/mediatek/Makefile b/arch/arm64/boot/dts/mediatek/Makefile index 4f68ebed2e31..e6c3a73b9e4a 100644 --- a/arch/arm64/boot/dts/mediatek/Makefile +++ b/arch/arm64/boot/dts/mediatek/Makefile @@ -7,6 +7,7 @@ dtb-$(CONFIG_ARCH_MEDIATEK) += mt6797-evb.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt6797-x20-dev.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7622-rfb1.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7622-bananapi-bpi-r64.dtb +dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-rfb.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt8167-pumpkin.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt8173-elm.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt8173-elm-hana.dtb diff --git a/arch/arm64/boot/dts/mediatek/mt7986a-rfb.dts b/arch/arm64/boot/dts/mediatek/mt7986a-rfb.dts new file mode 100644 index 000000000000..ca074cf8e578 --- /dev/null +++ b/arch/arm64/boot/dts/mediatek/mt7986a-rfb.dts @@ -0,0 +1,38 @@ +// SPDX-License-Identifier: (GPL-2.0 OR MIT) +/* + * Copyright (C) 2021 MediaTek Inc. + * Author: Sam.Shih + */ + +/dts-v1/;
