Ack, I can still change it to firmware-name if you want (Maxime has not yet
merged any dts changes using the touchscreen-fw-name). We should probably
also decide if the silead/ prefix we're using (so the firmware files are
/lib/firmware/silead/foo.fw under Linux) goes into the firmware-name
property as my current wip code is doing, or if we put the "silead/"
part in the driver and only put the part after it in the property.

I've a feeling that just putting only the base filename (so no "silead/"
prefix) in the property is best.

Hans
