Subject: [PATCH -rt 0/4] ARM: OMAP: Add clocksource and clockevent driver for OMAP

Hi,

the following patches for CONFIG PREEMPT RT add clocksource
and clockevent driver for ARM based TI OMAP devices.

They are against linux-2.6.19 + patch-2.6.20-rc1 +
patch-2.6.20-rc1-rt1. The clocksource patch went through
several review cycles on OMAP list.

Dirk

Btw: What's about

[PATCH -rt][RESEND] fix preempt hardirqs on OMAP
http://www.ussg.iu.edu/hypermail/linux/kernel/0612.1/0642.html

?

thanks. I've added them to the -rt tree and it should be in the next
release (2.6.20-rt2).

(a couple of small suggestions for future submissions: if you send them
as attachments (which is fine to me), please name patches canonically,
i.e. "arm-no-hz.patch", not "arm-no-hz-patch.txt" and include the patch
description in the patch file too - or just send it all as plaintext.
Plus please Cc: everyone who's involved with the patch(es) so that they
can see feedback too - in this case that would be Daniel Walker, Kevin
Hilman and David Brownell.)

that patch has problems because it breaks non-OMAP platforms. There was
a brief discussion about it but no updated patch AFAICS.

I just tried -rt3 (linux-2.6.19 + patch-2.6.20-rc1 +
patch-2.6.20-rc1-rt3) on embedded ARM based TI OMAP OSK
board. It compiles and boots without any additional patches :)

Hopefully -rt will be merged into mainline someday soon.

Thanks

Dirk
