FYI, looks like merging in your uart_v9 branch for testing
with my hwmod changes now fails to produce RX characters on omap3.

The device wakes up just fine to the wake-up interrupt, and then
serial8250_handle_irq() gets called, but I'm not seeing anything
in the console getting printed out. It's like all the RX characters
are getting lost instead of just the first one. The RX characters
work fine when the system is running.

So it seems there's been some kind of regression since v8?
