Shame. I understand the reasons behind that, but this source is rather stable (more so than some LKML archives ;-), and I copied the actual important information. But well, I guess people have to put it in their search engine and hope it doesn't drop them to the vendor's website ;-) > > > > Signed-off-by: Andre Przywara <andre.przywara@xxxxxxx> > > --- > > arch/arm64/boot/dts/allwinner/Makefile | 1 + > > .../allwinner/sun50i-h616-orangepi-zero2.dts | 203 ++++++++++++++++++ > > 2 files changed, 204 insertions(+) > > create mode 100644 arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi- > zero2.dts > > > > diff --git a/arch/arm64/boot/dts/allwinner/Makefile b/arch/arm64/boot/dts/ > allwinner/Makefile > > index 8fa5c060a4fe..df2214e6d946 100644 > > --- a/arch/arm64/boot/dts/allwinner/Makefile > > +++ b/arch/arm64/boot/dts/allwinner/Makefile > > @@ -38,3 +38,4 @@ dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h6-pine-h64.dtb > > dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h6-pine-h64-model-b.dtb > > dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h6-tanix-tx6.dtb > > dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h6-tanix-tx6-mini.dtb > > +dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h616-orangepi-zero2.dtb > > diff --git a/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dts b/ > arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dts > > new file mode 100644 > > index 000000000000..ca07cae698ce > > --- /dev/null > > +++ b/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dts > > @@ -0,0 +1,203 @@ > > +// SPDX-License-Identifier: (GPL-2.0+ or MIT) > > +/* > > + * Copyright (C) 2020 Arm Ltd. > > 2022? Mmh, but why? I wrote this in 2020, and it was published the first time that year[1]. If the copyright year means anything, by my understanding it should cover the earliest publication date, to establish the license conditions over every copy out there.
