Hi,
this should be correct (I'm using chip select 3 for this device)

Compatible describes the device, not the driver.  It takes the format
"vendor,device".  The node name, OTOH, is normally a generic description
of the device's functionality ("flash", "ethernet", "board-control",
etc).

You don't need #address-cells/#size-cells on the a3p400 node unless it
has child nodes with reg or ranges.
