[PATCH 5/7] Serial: OMAP: add runtime pm support for omap-serial driver

[Paul Walmsley]

Hi Govindraj,

what also would be good to find out is why the UART is apparently sending 
asynchronous wakeups even when the driver doesn't set 
SCR_REG.RX_CTS_WU_EN.  This seems contrary to the expectation that 34xx 
TRM vZH section 17.4.4.1.4.1 "Wake-up Interrupt" sets.  Could you please 
clarify under which circumstances the RX_CTS_WU_EN bit is used?  I suppose 
that, given that it's also mentioned under section 17.4.5.1.1 "Module 
Power Savings", it might only be used when SLEEP_MODE is enabled.
