I will apply it to the Aspeed tree in a few days, after giving others a chance to review. Out of interest, are you planning on running OpenBMC on this platform?

Yes, I will running OpenBMC on this platform. And In fact, the OpenBMC basic startup is already running on REP2. I'm also trying to push the OpenBMC patch for this platform. > Cheers, > > Joel > >> --- >> .../devicetree/bindings/vendor-prefixes.txt | 1 + >> arch/arm/boot/dts/Makefile | 1 + >> .../dts/aspeed-bmc-arm-stardragon4800-rep2.dts | 207 +++++++++++++++++++++ >> 3 files changed, 209 insertions(+) >> create mode 100644 arch/arm/boot/dts/aspeed-bmc-arm-stardragon4800-rep2.dts >> >> diff --git a/Documentation/devicetree/bindings/vendor-prefixes.txt b/Documentation/devicetree/bindings/vendor-prefixes.txt >> index 2c3fc51..c65c0c1 100644 >> --- a/Documentation/devicetree/bindings/vendor-prefixes.txt >> +++ b/Documentation/devicetree/bindings/vendor-prefixes.txt >> @@ -165,6 +165,7 @@ honeywell Honeywell >> hp Hewlett Packard >> holtek Holtek Semiconductor, Inc. >> hwacom HwaCom Systems Inc. >> +hxt Huaxintong Semiconductor Technology Co., Ltd. >> i2se I2SE GmbH >> ibm International Business Machines (IBM) >> idt Integrated Device Technologies, Inc. >> diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile >> index b5bd3de..a1b8816 100644 >> --- a/arch/arm/boot/dts/Makefile >> +++ b/arch/arm/boot/dts/Makefile >> @@ -1199,6 +1199,7 @@ dtb-$(CONFIG_ARCH_ZX) += zx296702-ad1.dtb >> dtb-$(CONFIG_ARCH_ASPEED) += \ >> aspeed-ast2500-evb.dtb \ >> aspeed-bmc-arm-centriq2400-rep.dtb \ >> + aspeed-bmc-arm-stardragon4800-rep2.dtb \ >> aspeed-bmc-intel-s2600wf.dtb \ >> aspeed-bmc-opp-lanyang.dtb \ >> aspeed-bmc-opp-palmetto.dtb \ >> diff --git a/arch/arm/boot/dts/aspeed-bmc-arm-stardragon4800-rep2.dts b/arch/arm/boot/dts/aspeed-bmc-arm-stardragon4800-rep2.dts >> new file mode 100644 >> index 0000000..83335c0 >> --- /dev/null >> +++ b/arch/arm/boot/dts/aspeed-bmc-arm-stardragon4800-rep2.dts >> @@ -0,0 +1,207 @@ >> +// SPDX-License-Identifier: GPL-2.0+ >> +/dts-v1/;
