 Hi Kgene,
 Can you take this patch if no issues with it.

 Is there any user for this function right now? Shouldn't this patch
 rather be included as a part of some series that adds actual users of it?

 Hi Tomasz,
 Exynos5420 patches have dependency on this.
 Those patches already posted.


Please ignore. Sending this with cpuidle patches



 Best regards,
 Tomasz

[PATCH] arm: exynos: add generic function to calculate cpu number

2014-04-24 Thread Chander Kashyap 
The address of cpu power registers in pmu is based on cpu number
offsets. This function calculate the same. This is essentially
required in case of multicluster SoC's e.g Exynos5420.
