Correction. The UART RX timeout is documented in section 17.4.4.1.3.7.1

Hello Govindraj
while trying to track down some of the serial-related PM issues in
v3.3-rc1, I noticed that the omap-serial.c driver sets a 1 microsecond
polling timer when DMA is enabled (uart_dma.rx_timer) (!) This seems
quite broken from both the DMA and PM points of view.
