mpc8xx CPM timer usage

mpc8xx CPM timer usage

[Robin Gilks]

Greetings

Does anyone know of any 'standard' Linux drivers that make use of any of
the 4 CPM timers?

I just want to check before the hardware guys caste our i/o lines into
stone :-))

Many thanks

When I used the DENX ELDK kernel on a custom MPC8XX board with serial
lines and Ethernet mostly, I once found no driver *used by the project*
that used the CPM timers. Note that we wrote our own SPI bus code,
though.

Your best bet is to check arch/ppc/8xx_io/*.[chS].

Why bother, since anyway they'll cast them the wrong way around?

The usb driver at http://www.heeltoe.com/software/usb/usb.html uses the
timers.
