This should be a generic property for all quad devices to use, though,

Full ACK, "m25p,dual-read" and "m25p,quad-read" sound like a good prop
names?

I was actually thinking something more generic than that - putting the
property at the SPI generic bindings level.  Though if all flashes with
this dual/quad read functionality have the prefix m25p the above would
work also, at the minute this does seem to be mostly used by flash (I
bet someone's got some DSPs or something though).

Ah! So you mean the SPI controller would provide information that it can do 
dual/quad transfers? But then, the additional pins can only be wired to certain 
chips (controller by certain CS lines).

Best regards,
