Add support for the bananapi R64 (BPI-R64) development board from BIPAI KEJI. Detailed hardware information for BPI-R64 which could be found on http://wiki.banana-pi.org/Banana_Pi_BPI-R64 Signed-off-by: Ryder Lee <ryder.lee@xxxxxxxxxxxx> --- changes since v1: - add missing sata nodes. - fix pinctrl-0 for pcie@1,0. - switch goio keys from polling mode to intterupt mode. - add gpio-led nodes. --- arch/arm64/boot/dts/mediatek/Makefile | 1 + .../boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts | 530 +++++++++++++++++++++ 2 files changed, 531 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts diff --git a/arch/arm64/boot/dts/mediatek/Makefile b/arch/arm64/boot/dts/mediatek/Makefile index 5b7fd6a..e8f952f 100644 --- a/arch/arm64/boot/dts/mediatek/Makefile +++ b/arch/arm64/boot/dts/mediatek/Makefile @@ -5,4 +5,5 @@ dtb-$(CONFIG_ARCH_MEDIATEK) += mt6795-evb.dtb dtb-$(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) += mt8173-evb.dtb diff --git a/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts b/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts new file mode 100644 index 0000000..5d6005c --- /dev/null +++ b/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts @@ -0,0 +1,530 @@ +/* + * Copyright (c) 2018 MediaTek Inc. + * Author: Ryder Lee <ryder.lee@xxxxxxxxxxxx> + * + * SPDX-License-Identifier: (GPL-2.0 OR MIT) + */ + +/dts-v1/;
