-Subject: spi: img-spfi: use device 0 configuration for all devices
-
-Given that we control the chip select line externally
-we can use only one parameter register (device 0 parameter
-register) and one set of configuration bits (port configuration
-bits for device 0) for all devices (all chip select lines).
