The PX30-µQ7 (Ringneck) is a system-on-module featuring the Rockchip PX30 in a micro Qseven-compatible form-factor. PX30-µQ7 features: * CPU: quad-core Cortex-A35 * DRAM: 2GB dual-channel * eMMC: onboard eMMC * SD/MMC * TI DP83825I 10/100Mbps PHY * USB: * USB2.0 dual role port * 3x USB2.0 host via onboard USB2.0 hub * Display: MIPI-DSI * Camera: MIPI-CSI * onboard 2.4GHz WiFi + Bluetooth module * Companion Controller: on-board additional microcontroller (STM32 Cortex-M0 or ATtiny): * RTC * fan controller * CAN (only STM32) The non-U-Boot DTS files are imported from Linux v6.2-rc2.
