The S3C64xx SoCs contain a set of gateable power domains which can be
enabled and disabled at runtime in order to save power. Use the generic
power domain code to implement support for these in software, enabling
runtime control of most domains:
- ETM (not supported in mainline).
- Domain G: 3D

I've resent it
Hello Linus,
sorry for the delay in submitting V3 of the pl080 patches for s3c64xx.
I am very busy with my current assignment.
I will come back to my patch series incorporating yours and Viresh
suggestions in v3.
Thanks!!

The of_irq_init function would be setup to invoke the exynos4_init_irq_eint
function when booting using device tree. The arch_initcall for
exynos4_init_irq_eint would duplicate its invocation in that case. Hence,
arch_initcall for exynos4_init_irq_eint is removed and this function is invoked
from t
The exynos4_get_irq_nr function that converts a given wakeup interrupt
source number to a linux irq number is simplified and replaced with
the new macro exynos4_irq_eint_to_gic_irq.

Samsung Exynos4 includes 32 external wakeup interrupt sources. This patchset
adds irq domain and device tree support for these interrupts.
This patchset is based on the following tree.

Hi all,
Here I have to measure time elapsed between two events in
microseconds. Currently in my working kernel 2.6.36.2, there is no
support for high resolution timer and resolution of time is 10ms
(jiffies) . Can you please help me to get high resolution timer? Or Do
I have to use timer hardware
