Orange Pi Zero is a board that came with the new Allwinner H2+ SoC. Add a device tree file for it. Signed-off-by: Icenowy Zheng <redacted> --- Changes since v2: - Use generic pinconf binding instead of legacy allwinner pinctrl binding. - removed uart3, which is not accessible on Orange Pi Zero. - Removed sun8i-h2plus.dtsi and make Orange Pi Zero dts directly include sun8i-h3.dtsi. - Removed allwinner,sun8i-h3 compatible. arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/sun8i-h2plus-orangepi-zero.dts | 137 +++++++++++++++++++++++ 2 files changed, 138 insertions(+) create mode 100644 arch/arm/boot/dts/sun8i-h2plus-orangepi-zero.dts
