Subject: Re: i.MX SPI driver

Hi Sascha,

Sorry for late replay!
The current driver support DMA transfers.
Surely for our design this feature is mandatory since we need to sustain 
heavy SPI traffic.
I suggest to not remove the driver even if it only supports iMX1 device 
and not the entire family.
Is it possible to have both current and new drivers?

Regards,
Andrea
