as you said, I removed the code in 1) so the EBUSY error is gone.

What is with the spi_irq = -1 ?? is this a problem here?

the message "no flags found for reset" seems also ok, but it does not
read the device id yet,
 what else can be wrong here?

In previous mails I added the _CRS for this device WM510202, is the
gpio-mapping, with its indexes ok so far??

The last two messages are clear to me.
I will add the machine driver if the device id was read correctly etc.

cheers
chris
