From: Tao Ren <rentao.bupt@xxxxxxxxx> Add initial version of device tree for Facebook Cloudripper (AST2600) BMC. Cloudripper is Facebook's next generation switch platform with an AST2600 BMC integrated for health monitoring purpose. Signed-off-by: Tao Ren <rentao.bupt@xxxxxxxxx> --- Changes in v2: - added more notes about the new platform in patch description. - "spi1" was removed as the driver is not ready. - "mac3" properties were updated with pinctrl, and etc. arch/arm/boot/dts/Makefile | 1 + .../dts/aspeed-bmc-facebook-cloudripper.dts | 539 ++++++++++++++++++ 2 files changed, 540 insertions(+) create mode 100644 arch/arm/boot/dts/aspeed-bmc-facebook-cloudripper.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 90aed2c2959a..74c760038f28 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1409,6 +1409,7 @@ dtb-$(CONFIG_ARCH_ASPEED) += \ aspeed-bmc-arm-stardragon4800-rep2.dtb \ aspeed-bmc-asrock-e3c246d4i.dtb \ aspeed-bmc-bytedance-g220a.dtb \ + aspeed-bmc-facebook-cloudripper.dtb \ aspeed-bmc-facebook-cmm.dtb \ aspeed-bmc-facebook-galaxy100.dtb \ aspeed-bmc-facebook-minipack.dtb \ diff --git a/arch/arm/boot/dts/aspeed-bmc-facebook-cloudripper.dts b/arch/arm/boot/dts/aspeed-bmc-facebook-cloudripper.dts new file mode 100644 index 000000000000..01ec3ce0a29d --- /dev/null +++ b/arch/arm/boot/dts/aspeed-bmc-facebook-cloudripper.dts @@ -0,0 +1,539 @@ +// SPDX-License-Identifier: GPL-2.0+ +// Copyright (c) 2020 Facebook Inc. + +/dts-v1/;
