In our application of the DM6446, we require to momentarily (few seconds) tri-state the SPI bus.
We are running Linux 2.6.18+ under MontaVista 5.
Can some-one kindly guide me as to how to accomplish this under Linux?
Our current work-around is to RESET the DM6446 and reboot Linux, which does the job, but is far from ideal.
Any help is greatly appreciated.
