The hardware is described in detail on Kobol's wiki at https://wiki.kobol.io/helios64/intro/. Up to now the following peripherals are working: - UART - Micro-SD card - eMMC - ethernet port 1 - status LED - temperature sensor on i2c bus 2 Signed-off-by: Uwe Kleine-König <uwe@kleine-koenig.org> --- arch/arm64/boot/dts/rockchip/Makefile | 1 + .../dts/rockchip/rk3399-kobol-helios64.dts | 382 ++++++++++++++++++ 2 files changed, 383 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3399-kobol-helios64.dts
