Not a misc device. Find appropriate place, e.g. for EC or docking or
laptop devices or power-related.

Way too generic compatible. You are not documenting here all ASUS
laptops/devices dockram. For example this implies dockram is also on
ASUS Vivobook... or on any other asus device.

handle, so what you really wanted is i2c-parent. This is not a real
device.
