During kernel build process, the following warning was found:

these warnings. These changes also apply to s3c2400 & s3c24a0 for consistency.

When SERIAL_ATMEL_CONSOLE is disabled, ATMEL_CONSOLE_DEVICE is set to

atmel_serial_probe makes the compile fail.  This fixes the issue by only
accessing it if CONFIG_SERIAL_ATMEL_CONSOLE is defined

44e18e9eda sh-sci: update receive error handling for muxed irqs
This patch updates the receive error code for muxed
interrupts in the sh-sci driver.

Receive error interrupts may be generated by the hardware
if RE or REIE bits in SCSCR are set. Update the muxed
interrupt handling code to acknowledge error interrupts
if RE or REIE is set, instead of only acknowledging if
REIE is set.

Without this patch error interrupts may be generated but
never acked resulting in a "nobody cared" crash.

52e3632ea6 serial: fix off by one errors
In zs_console_putchar() occurs:

	if (zs_transmit_drain(zport, irq))
		write_zsdata(zport, ch);

However if in zs_transmit_drain() no empty Tx Buffer occurs, limit reaches
-1 => true, and the write still occurs.

This patch changes postfix to prefix decrements in this and similar
functions to prevent similar mistakes in the future.  This decreases the
iterations with one but the chosen loop count was arbitrary anyway.

In sunhv limit reaches -1, not 0, so the test is off by one.

waiting for the transmitter to drain.  This appears to be caused by a
busy-loop in set_termios() waiting for the transmitter to become empty,
which may take a very long time (or hang indefinitely) if the device at
the other end is blocking us.

A quick look through the tty and serial_core code indicates that any
necessary flushing (which is optional) has already been done at this
point, so there's no need for the driver to flush the transmitter on its
own.

Fix it by removing the busy-loop altogether.

3cf62a5a82 of_serial: remove driver_data direct access of struct device
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

eedacbf02d of_serial: Add UPF_FIXED_TYPE flag
This patch adds the UPF_FIXED_TYPE flag which will bypass the
8250's autoconfig probe for uart type. The uart type identified
by the of_serial's parse of the flat device tree will be utilized
as defined.

b45cc9eff7 serial: Make ucc_uart work in HW UART mode
In HW UART mode the TxBD[READY] is not cleared by H/W (RISC engine) when
the user send characters to Tx buffer of QE UART.  So, these characters
stay on the QE forever, never go to UART line.
