arm64: dts: rockchip: add roc-rk3328-cc board
The roc-rk3328-cc is a credit card size single board computer using the Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supporting up to 2GB 2133MHz LPDDR4 memory. It provides eMMC module socket, MicroSD Card slot, USB 2.0/3.0, Gigabit Ethernet, HDMI/CVBS, Infrared Receiver, SPDIF/I2S, and SPI/I2C/UART/PWM interfaces. The devicetree currently supports basic peripherals. Signed-off-by: Levin Du <djw@t-chip.com.cn> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
