arm64: dts: rockchip: add wolfvision pf5 io expander board
Add device tree overlay for the WolfVision PF5 IO Expander board. This extension board can be attached to the WolfVision PF5 mainboard and features - TI DP83826 Ethernet PHY - RJ45 jack - USB-A host port Signed-off-by: Michael Riesch <michael.riesch@wolfvision.net> Link: https://lore.kernel.org/r/20240325-feature-wolfvision-pf5-v1-4-5725445f792a@wolfvision.net Signed-off-by: Heiko Stuebner <heiko@sntech.de>
