DS1337 RTC on I2C broken.

[raul.moreno at telvent.abengoa.com]

Hello all,

I am trying to use some devices on i2c protocol, one of them is the DS1337
RTC, but I don't know too much about how.
I am using the Linux kernel 2.6.15 and a mpc866 processor. I've seen there
is a cpm i2c interface for these processors (for a rpx board). However the
corresponding code (i2c-algo8xx) doesn't appear in the sources. The
i2c-rpx.c just initializes the ioports, the adapter struct and the isr.
Maybe I am not understanding the i2c driver right.
I am a bit confused about it. Could you give me some help about how it
works or what should I have to do?

Thanks in advance.
Best regards,

Raúl Moreno

Just to give you an update: The latest paulus.git as of today
(Linux-2.6.24-rc3-g0b47759d) is still broken. Same story as yesterday.
