1b41dbc129 serial: omap-serial: Add support for kernel debugger 
The kgdb invokes the poll_put_char and poll_get_char when communicating
with the host. This patch also changes the initialization order because the
kgdb will check at the very beginning, if there is a valid serial
driver.

79fc3e2140 serial: omap-serial: fix signess error 
"ret" is unsigned, so check for (ret < 0) made no sense.
Made it signed.

b612633b59 serial: Add OMAP high-speed UART driver 
This patch adds driver support for OMAP2/3/4 high speed UART.

The driver is made separate from 8250 driver as we cannot
over load 8250 driver with omap platform specific configuration for
features like DMA, it makes easier to implement features like DMA and
hardware flow control and software flow control configuration with
this driver as required for the omap-platform.
This patch involves only the core driver and its dependent.
