PPC RTC on I2C

Hey all,

I'm working on getting i2c support working on a module that has its RTC on i2c.

I've got my i2c client written, but i2c-core and friends don't load until very late in the game; setting ppc_md.get/set (at least in platform_init) is not very useful.

Any thoughts on a graceful way to implement kernel RTC support using an i2c-based RTC (w/o bypassing the kernel's i2c layer)?

Apologies if I've missed something obvious.

Regards,
Tim

Hi,

I've been away from the list for a few months and would appreciate
some larger context w/ that comment and cflags in Makefile --

I'm confused as include/linux/kernel.h includes stdarg.h, but
the 'extra cflags' specify: -nostdinc -iwithprefix include,
causing this inclusion not to be satisfied ...

commenting out:
kbuild_2_4_nostdinc	:= -nostdinc -iwithprefix include
export kbuild_2_4_nostdinc

causes the build to compile better.

my apologies if I've missed something here;

Mark

Why not use RTC in the PPC core?

Hi all

Does anyone know of a QMC driver for the PPC860?
It does not have to be perfect, I will take anything since
I have not been in this area before.

 Thanks

I have something that works for the MPC850.
Unfortunately it is kinda complex and too much tied
to my custom hardware to be of any use directly.
I.e. be prepared to hack it a bit. Email me if you are interested...

Yes, please sent it. I am interested in any driver I can get my hands on.
Even if it's not directly usable, I can always learn from it.

Anybody else that have a QMC driver, please don't hesitate to send me a copy.

 Thanks
