serial: small Makefile reordering

2017-04-18T16:01:52+00:00

Move 21285 entry down alongside other UART drivers to be more consistent
with the rest of the file. It is kept before 8250 though, to preserve the
existing link ordering between those two.

tty: serial: Makefile: move kgdb to be initialized last

2016-10-27T14:27:24+00:00

fsl_lpuart cannot be used with kgdb because the kgdb
initcall is called before the driver's init.
Move kgdb to be initialized after all serial drivers
have been inited.

serial: rewrite pxa2xx-uart to use 8250_core

2016-10-27T14:03:09+00:00

pxa2xx-uart was a separate uart platform driver. It was declaring
the same device names and numbers as 8250 driver. As a result,
it was impossible to use 8250 driver on PXA SoCs.

Upon closer examination pxa2xx-uart turned out to be a clone of
8250_core driver.

Workaround for Erratum #19 according to Marvel(R) PXA270M Processor
Specification Update (April 19, 2010) is dropped. 8250_core reads
from FIFO immediately after checking DR bit in LSR.

The patch leaves the original SERIAL_PXA driver around. The original
driver is just marked DEPRECATED in Kconfig and C source. When
the original driver is considered safe to remove, no changes
to SERIAL_8250 will be necessary.

Compiling SERIAL_8250_CONSOLE and SERIAL_PXA_CONSOLE even without
SERIAL_8250_PXA breaks console for SERIAL_PXA. For this reasons, the new
and the original drivers are made mutually exclusive.

Merge tag 'tty-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

2016-05-21T03:57:27+00:00

Pull tty and serial driver updates from Greg KH:
 "Here's the large TTY and Serial driver update for 4.7-rc1.

  A few new serial drivers are added here, and Peter has fixed a bunch
  of long-standing bugs in the tty layer and serial drivers as normal.
  Full details in the shortlog.

  All of these have been in linux-next for a while with no reported
  issues"

serial: mvebu-uart: initial support for Armada-3700 serial port

2016-03-08T00:11:14+00:00

Armada-3700's uart is a simple serial port, which doesn't
support. Configuring the modem control lines. The uart port has a 32
bytes Tx FIFO and a 64 bytes Rx FIFO

The uart driver implements the uart core operations. It also support the
system (early) console based on Armada-3700's serial port.

Known Issue:

The uart driver currently doesn't support clock programming, which means
the baud-rate stays with the default value configured by the bootloader
at boot time

serial: 8250: move of_serial code to 8250 directory

2015-12-14T03:59:48+00:00

As the of-serial driver is now 8250 specific, we can move the
file to a more appropriate place in teh 8250 subdirectory and
adapt the Kconfig help text and file name.

I'm leaving the CONFIG_SERIAL_OF_PLATFORM symbol unchanged
to avoid breaking user configuration files unnecessarily.
