I am currently doing port for already working PQ2 board (MPC8270) from "ppc" to
"powerpc" architecture.
When initial port took place, the driver i2c-cpm that appeared on linuxppc list
in the beginning of 2006 was used,
and it is working perfectly all this time.
However, when I am trying to use the driver in your patch, I encountered the
following problem :
Your driver loads and probes perfectly well, however any attempt to read
anything from the bus times out.
Receive never takes place. To make things works, If a user-space program is
interrupted by ctrl-c while waiting for data, the driver enters an endless
loop, that effectively kills the kernel.
can you suggest any solution for this problem?
I, also, suggest moving BRG setup values to the device tree instead of
hard-coding them into the driver.
