Status of I2C on mpc5200

[Eric DUJARDIN]

Hello all,

I have a question regarding the stability of I2C on mpc52xx.
According to menuconfig's help it isn't still stable as it says:
"The driver may also work on 52xx family processors, though interrupts are 
known not to work"

However there has been a patch from Domen Puncer that apparently fixed the 
driver in 2.6.23.

commit 254db9b5e7b1b0d38a4f177c2c23a5685c78221a

    i2c-mpc: work around missing-9th-clock-pulse bug
 
    Work around a problem reported on:
    http://ozlabs.org/pipermail/linuxppc-embedded/2005-July/019038.html
    Without this patch I2C on mpc5200 becomes unusable after a while.
    Tested on mpc5200 boards by Matthias Fechner and me.

If any kind soul could provide a status I'd be glad to provide the patch 
for the help file...
Thanks,

Eric Dujardin
