Habidere, This series adds the device tree for the WolfVision PF5 mainboard, which serves as base for recent WolfVision products. It features the Rockchip RK3568 and can be extended with several different extension boards. The WolfVision PF5 IO Expander is one example of such an extension board. The corresponding device tree overlay is also included in this series. May this be the beginning of a beautiful friendship :-) Looking forward to your comments!
