My general idea is to get overlay loading to work and then make spidev bind to all CS which are not taken by anything and unbind when an overlay tries to take over the CS. Since there are some overlay loading patches available that part can be considered solved but I did not get to looking at the dynamic spidev binding. For now I use your patch with additional patch that marks the spidev devices with a flag so they are not checked when it is determined if the CS is in use.
