From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx> Add devicetree for Bananapi R3 Mini SBC. Key features: - MediaTek MT7986A(Filogic 830) Quad core ARM Cortex A53 - Wifi 6 2.4G/5G (MT7976C) - 2G DDR RAM - 8G eMMC flash - 128MB Nand flash - 2x 2.5GbE network port - 1x M.2 Key B USB interface - 1x M.2 KEY M PCIe interface - 1x USB2.0 interface source: https://wiki.banana-pi.org/Banana_Pi_BPI-R3_Mini Co-developed-by: Eric Woudstra <ericwouds@xxxxxxxxx> Signed-off-by: Eric Woudstra <ericwouds@xxxxxxxxx> Co-developed-by: Tianling Shen <cnsztl@xxxxxxxxx> Signed-off-by: Tianling Shen <cnsztl@xxxxxxxxx> Signed-off-by: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx> Reviewed-by: Daniel Golle <daniel@xxxxxxxxxxxxxx> --- v3: - changed unicode parentheses in commit description - added reviewed by v2: - add missing node for nand - add some information about the board in description change dts based on review from angelo+krzysztof - drop fan status - rename phy14 to phy0 and phy15 to phy1 - drop default-trigger from phys and so also the binding-patch - use regulator names based on regexp regulator-[0-9]+v[0-9]+ - add comment for pwm --- arch/arm64/boot/dts/mediatek/Makefile | 1 + .../mediatek/mt7986a-bananapi-bpi-r3-mini.dts | 493 ++++++++++++++++++ 2 files changed, 494 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts diff --git a/arch/arm64/boot/dts/mediatek/Makefile b/arch/arm64/boot/dts/mediatek/Makefile index 37b4ca3a87c9..1763b001ab06 100644 --- a/arch/arm64/boot/dts/mediatek/Makefile +++ b/arch/arm64/boot/dts/mediatek/Makefile @@ -11,6 +11,7 @@ dtb-$(CONFIG_ARCH_MEDIATEK) += mt7622-bananapi-bpi-r64.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7981b-xiaomi-ax3000t.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-acelink-ew-7886cax.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3.dtb +dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-mini.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-emmc.dtbo dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-nand.dtbo dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-nor.dtbo diff --git a/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts b/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts new file mode 100644 index 000000000000..e2a2fea7adf0 --- /dev/null +++ b/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts @@ -0,0 +1,493 @@ +// SPDX-License-Identifier: (GPL-2.0 OR MIT) +/* + * Copyright (C) 2021 MediaTek Inc. + * Authors: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx> + * Eric Woudstra <ericwouds@xxxxxxxxx> + * Tianling Shen <cnsztl@xxxxxxxxxxxxxxx> + */ + +/dts-v1/;
