[PATCH] rtc: at91sam9: include <mach/hardware.h> explicitly

[PATCH] rtc: at91sam9: include <mach/hardware.h> explicitly

[Uwe Kleine-König]

The driver needs the symbol AT91_SLOW_CLOCK which is defined in
arch/arm/mach-at91/include/mach/hardware.h. This file is included
implicitly via linux/module.h -> linux/kmod.h -> linux/gfp.h ->
linux/mmzone.h -> linux/memory_hotplug.h -> linux/notifier.h ->
linux/srcu.h -> linux/workqueue.h -> linux/timer.h -> linux/ktime.h ->
linux/jiffies.h -> linux/timex.h -> mach/timex.h -> mach/hardware.h .

So better include it explicitly not only because the last link will go
away soon.

we should never use this symbol you need to request the clock clk32k

IMHO this should be addressed in another patch. My intent is to get rid
of <mach/timex.h>. So I let someone else take this patch opportunity.

Ping. Is this patch ok despite Jean-Christophe's objection?

This patch is one of the last few that are needed to drop <mach/timex.h>
alltogether that I don't have an ack from the respective maintainer yet.

Can you give your ack instead of sending the patch to Linus, then I'd
take it with the patch dropping <mach/timex.h> to make it easier to
merge.

Thanks
Uwe

I understand the objective of this patch.

So, in the meantime, you have my:

thanks. There is another rtc change that I didn't receive any feedback
for from a maintainer:

	rtc: pxa: drop unused #define TIMER_FREQ

. In the meantime I send a pull request asking to ignore that I didn't
get any maintainer reply for the rtc changes. Do you think it's sensible
to change the entry in MAINTAINERS? Any combination of:

	a) drop Alessandro's M: line
	b) add you
	c) change Status from Maintained to Odd Fixes or Orphan

> I dropped my copy.
fine, thanks

I'll wait for some time now before adding your ack to my tree to prevent
that you give me an ack for the other change just when I sent a new pull
request :-)

ack.  Robert Jarzmik also acked that one.

Yeah, I should have a couple hundred MAINTAINERS entries.  Instead I
just lurk on mailing lists ;)

Thanks, I saw Robert Jarzmik's ack, but for taking a $subsystem1 patch through
the $subsystem2 tree, I like to have an ack of the maintainer of
$subsystem1. And in this regard I think yours is better than Robert's
(who is the original author of the driver).

So only a) and c).
