This patch implements PMC wakeup sequence for Tegra210 and defines
common used wake events of RTC alarm and power key.

Hi Sowjanya,

usleep_range() in tegra210_pmc_irq_set_wake() should be replaced with 
udelay() because caller irq_set_irq_wake() acquired spinlock and made 
this context atomic.

Thanks,

JC

Do we really need this? It's only used in Tegra210 specific code and
it's always 64 on Tegra210. Can't we always hard-code it?

Blank line before and after the "value = ..." line, for readability.

Same here, leave a blank line before the tegra_pmc_writel(...) call to
improve readability.

Same comment as above.

Otherwise, looking good, thanks.
