The device tree for the WolfVision PF5 mainboard and the overlay for
the PF5 IO Expander have been accepted for inclusion in Linux v6.10:
https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/log/?h=v6.10-armsoc/dts64
Once the device tree changes are merged and then integrated into
barebox this commit should vanish.
