> Please pull the OMAP UART cleanup and conversion to runtime PM.  I had
> to rebase it onto your soc branch due to the serial.c changes there.
> 
> This includes changes to drivers/tty/serial/omap-serial.c and those
> changes have Acks from Greg KH and Alan Cox and I got the OK from them
> to merge this all together via the OMAP tree.
> 
> Thanks to Govindraj for his persistence with this series.
> 
> Boot tested on 2420/n810, 4430/Blaze, 4430/Panda
> Additional PM testing on 3430/n900, 3530/Overo, 3630/Zoom3.
> 
> NOTE: while normal UART behavior works fine with this series, including
>       suspend/resume, in order for wakeups from runtime PM to work, this
>       series depends on the PRCM IRQ chaining series from Tero and the
>       the new hwmod init state from Rajendra[1].  However, since runtime
>       PM is disabled by default for the UARTs, they will behave normally
>       even without those dependencies.
