It has GPIO buttons on the face and side for input, a single mono speaker, a 240x240 SPI controlled display, a USB-C OTG port, an SD card slot for booting, and 64MB of RAM included in the SoC. The SPI display is currently unsupported, as it will either require a new tinydrm driver or changes to the staging fbtft driver to support. I plan on working on a tinydrm driver to properly support it. The USB-C port currently only works as a peripheral port, however in the BSP kernel it also works in host mode allowing included USB-C headphones with a built-in DAC to work. Working: - SDMMC - UART (for debugging) - Buttons - Charging/battery/PMIC - Speaker - USB Gadget Not working: - Display - USB Host Signed-off-by: Chris Morgan --- arch/arm/boot/dts/allwinner/Makefile | 1 + .../allwinner/sun8i-v3s-anbernic-rg-nano.dts | 219 ++++++++++++++++++ 2 files changed, 220 insertions(+) create mode 100644 arch/arm/boot/dts/allwinner/sun8i-v3s-anbernic-rg-nano.dts diff --git a/arch/arm/boot/dts/allwinner/Makefile b/arch/arm/boot/dts/allwinner/Makefile index 589a1ce1120a..2be83a1edcbb 100644 --- a/arch/arm/boot/dts/allwinner/Makefile +++ b/arch/arm/boot/dts/allwinner/Makefile @@ -237,6 +237,7 @@ dtb-$(CONFIG_MACH_SUN8I) += \ sun8i-t113s-mangopi-mq-r-t113.dtb \ sun8i-t3-cqa3t-bv3.dtb \ sun8i-v3-sl631-imx179.dtb \ + sun8i-v3s-anbernic-rg-nano.dtb \ sun8i-v3s-licheepi-zero.dtb \ sun8i-v3s-licheepi-zero-dock.dtb \ sun8i-v40-bananapi-m2-berry.dtb diff --git a/arch/arm/boot/dts/allwinner/sun8i-v3s-anbernic-rg-nano.dts b/arch/arm/boot/dts/allwinner/sun8i-v3s-anbernic-rg-nano.dts new file mode 100644 index 000000000000..c49b5431d04e --- /dev/null +++ b/arch/arm/boot/dts/allwinner/sun8i-v3s-anbernic-rg-nano.dts @@ -0,0 +1,219 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) + +/dts-v1/;
