Subject: [PATCH v2 2/2] arm64: dts: rockchip: Add basic support for Kobol's Helios64
Date: Mon, 12 Oct 2020 22:43:17 +0200
Message-ID: <20201012204317.1581752-3-uwe@kleine-koenig.org> (raw)
In-Reply-To: <20201012204317.1581752-1-uwe@kleine-koenig.org>

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
