Hi Daniel,

These are the ARM/ARM64 arch timer updates for v3.12.
I have re-based the changes on tip/timers/core as there are conflicts with memory mapped arch_timers support queued recently. Since this series adds CPU PM notifiers for arch_timers, it is required to enable ARM bL cpuidle drivers(already queued for v3.12)

Regards,
Sudeep

Hi Sudeep,

I need the acked-by from Olof or Kevin for the arch/arm[64] changes.

Thanks

For 3.12? Too late. Ping me after the mere window for a 3.13 ack instead.

Thanks,

Hi Sudeep,
I need the acked-by from Olof or Kevin for the arch/arm[64] changes.

Hi Daniel,

I think the changes are more generic to arm/arm64, rather not SoC specific. Catalin has reviewed the series. I can check with Russell(for arm) and Catalin(for arm64) for Acks.
I do understand that it may be late for v3.12

Regards,
Sudeep
