Message-ID<rsGhH-P8-3@gated-at.bofh.it>
I ended up stuffing the two patch series into one, as they are now
more dependent on one another. This now thoroughly removes the
genrtc driver including the asm/rtc.h headers it uses. For all
architectures that still have a meaningful asm/rtc.h, this goes
through two stages:

1) make the rtc-generic implementation independent of asm/rtc.h
2) remove the asm/rtc.h header and disallow the gen_rtc driver

As the last step, the driver itself gets removed.

#1389680 — [PATCH v3 09/16] rtc: m68k: provide rtc_class_ops directly

Subject[PATCH v3 09/16] rtc: m68k: provide rtc_class_ops directly
Message-ID<rsGB4-X9-15@gated-at.bofh.it>
In reply to#1389679
The rtc-generic driver provides an architecture specific
wrapper on top of the generic rtc_class_ops abstraction,
and m68k has another abstraction on top, which is a bit
silly.

This changes the m68k rtc-generic device to provide its
rtc_class_ops directly, to reduce the number of layers
by one.

Oops, I was planning to remove the comment here.

I probably have to do a v4 anyway, fixed it up locally now.

More build coverage uncovered two build failures on m68k due to "[PATCH v3
02/16] rtc: cmos: move mc146818rtc code out of asm-generic/rtc.h":

bvme6000_defconfig:

These do not show up with a multi-platform config including Atari
support, as arch/m68k/include/asm/mc146818rtc.h provides a definition of
CMOS_READ() if CONFIG_ATARI=y.

Fortunately the fixes are simple: replace <linux/mc146818rtc.h> by
<linux/rtc.h>. Will send patches to fix...

Hi Arnd,

I see you didn't copy Greg on that series (that may explain his
confusion on the previous patch), do you expect me to take it
through the RTC tree? That is fine but I'd like some acks from him.

Yes, that was a mistake. I dropped Greg from one Cc list in v2 when
I split up the RTC changes into the part that was for drivers/rtc
and the other one for Greg's char-misc tree. Then I reused the first
Cc list when I sent a combined series for v3 again. I'll fix that
when I post v4. There are only very small changes in there that
I still need to pick up, so hopefully that will be the last version.

It would be nice if you could take it through your tree then.
