Looks alright, the same story here with the DT. I updated to v3, with the prospect of updating this later in the cycle when needed. I dropped the Ethernet support from the defconfig for now, as I moved the EMAC driver fixes out of this initial series. Ideally we can still get them merged next week. > > Signed-off-by: Jernej Skrabec <[email protected]> Reviewed-by: Andre Przywara <[email protected]> Cheers, Andre > --- > arch/arm/dts/Makefile | 2 + > arch/arm/dts/sun50i-h616-orangepi-zero2.dts | 240 ++++++++++++++++++++ > board/sunxi/MAINTAINERS | 5 + > configs/orangepi_zero2_defconfig | 15 ++ > 4 files changed, 262 insertions(+) > create mode 100644 arch/arm/dts/sun50i-h616-orangepi-zero2.dts > create mode 100644 configs/orangepi_zero2_defconfig > > diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile > index 1a62e4c0708a..ed6150dca38d 100644 > --- a/arch/arm/dts/Makefile > +++ b/arch/arm/dts/Makefile > @@ -609,6 +609,8 @@ dtb-$(CONFIG_MACH_SUN50I_H6) += \ > sun50i-h6-orangepi-lite2.dtb \ > sun50i-h6-orangepi-one-plus.dtb \ > sun50i-h6-pine-h64.dtb > +dtb-$(CONFIG_MACH_SUN50I_H616) += \ > + sun50i-h616-orangepi-zero2.dtb > dtb-$(CONFIG_MACH_SUN50I) += \ > sun50i-a64-amarula-relic.dtb \ > sun50i-a64-bananapi-m64.dtb \ > diff --git a/arch/arm/dts/sun50i-h616-orangepi-zero2.dts > b/arch/arm/dts/sun50i-h616-orangepi-zero2.dts > new file mode 100644 > index 000000000000..2afc036059b4 > --- /dev/null > +++ b/arch/arm/dts/sun50i-h616-orangepi-zero2.dts > @@ -0,0 +1,240 @@ > +// SPDX-License-Identifier: (GPL-2.0+ or MIT) > +/* > + * Copyright (C) 2020 Arm Ltd. > + */ > + > +/dts-v1/;
