[PATCH v4 08/11] tty: add pruss SUART driver

[Subhasish Ghosh]

Hi Greg,

I am observing a RX FIFO sized data loss problem with my driver.

I observed that if I start the TX before the RX, then there are no errors,
but, if I start a TX after a RX, then I observe the error (FIFO sized data 
chunks missing).

Say, for example, if I use all three UARTS and on all three I start RX, then 
for every TX started I would observe
one error on all the RX data buffer.

So, if I start only two TX, then I will see only two errors on all the three 
RX UARTS.
