Cover letter [PATCH 0/2] Use Exynos-MCT timer as wakeup for Arm arch timer
Hi all,
These two patches build on top of my other series for adding per-cpu wakeup timers [1] which is currently queued in -tip [2].
The basic idea is to prefer the Arm architected timer, even when CLOCK_EVT_FEAT_C3STOP is set, as long as we have another timer which can be used for the per-cpu wakeup. These patches use Exynos-MCT as an example, since that driver currently goes out of its way to prevent use of the Arm architected timer due to issues with a 32-bit SoC.
Cheers,
Will
