Some TongFang barebones have touchpad and/or keyboard issues after
suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of
them have an external PS/2 port so this can safely be set for all of
them.
I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use, no negative effects could be
observed when setting all four.
