NanoPi M1 is a board based on Allwinner H3 CPU. This commit adds the support for this platform with: - an include device tree which enables UART, LEDs, GPIO key switch, 1 USB host ports and the SD-card as a dtsi file. - a device tree specific to this board that enables the 2 additional USB ports - a defconfig file for minimal support - a section in MAINTAINERS (add myself) Synchronized with the kernel device tree, from commits: sun8i-nanopi.dtsi: 85d2913614d9ab899d23b7ab7d22d23cf45bd1de sun8i-h3-nanopi-m1.dts: 10efbf5f16336b7540ad6a16aa1cb0b26bab033b Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>master
