Mmm you mean patch 4 I think. Then I'd like you too, because it's linked in the serie, and without it the former non-DT platforms break, hence I'd like all the serie to go through 1 tree. Yet we'd need Haojian's ack here. Haojian, would you give your blessing on the serie and agree that Daniel carries all the patches including patch 4/4 ? Cheers. -- Robert

Haojian, would you review this one please ? It's here : http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/272311.html Cheers.

As clocksource pxa_timer was moved to clocksource framework, the pxa_timer initialization needs to be a bit amended, to pass the necessary informations to clocksource, ie : - the timer interrupt (mach specific) - the timer registers base (ditto) - the timer clockrate Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> --- Since V2: Arnd's comment : moved extern declaration into .h file --- arch/arm/mach-pxa/generic.c | 11 +++++++++++ include/clocksource/pxa.h | 18 ++++++++++++++++++ 2 files changed, 29 insertions(+) create mode 100644 include/clocksource/pxa.h
