Fixed up conflicts in drivers/serial/apbuart.c with evil merge that
makes the code look fairly sane (unlike either side).

Cosmin Cojocar 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.

Andrei Emeltchenko 662b083a87 omap: Serial: Define register access modes in LCR
Access to some registers depends on register access mode
Three different modes are available for OMAP (at least)
• Operational mode     LCR_REG[7] = 0x0
• Configuration mode A LCR_REG[7] = 0x1 and LCR_REG[7:0]! = 0xBF
• Configuration mode B LCR_REG[7] = 0x1 and LCR_REG[7:0]  = 0xBF

Define access modes and remove redefinitions and magic numbers
in serial drivers (and later in bluetooth driver).

Andrei Emeltchenko 498cb95175 OMAP: Serial: Define OMAP uart MDR1 reg and remove magic numbers
Define MDR1 register serial definitions used in serial and
bluetooth drivers.
Change magic number to ones defined in serial_reg for omap1/2
serial driver.
Remove redefined MDR1 register definitions in omap-serial driver.

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

Govindraj.R 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.
