serial: Unneeded ARCH dependencies are removed

2012-11-16T01:11:42+00:00

This patch performs a small cleanup tty/Serial/Kconfig file by removing
unneeded ARCH dependencies. This dependencies already included in
board/type symbols.

serial: xilinx_uartps: kill CONFIG_OF conditional

2012-11-16T00:58:19+00:00

The Zynq platform requires the use of CONFIG_OF.  Remove the #ifdef
conditionals in the uartps driver.  Make dependency explicit in Kconfig.

tty/serial: Add kgdb_nmi driver

2012-09-26T20:52:36+00:00

This special driver makes it possible to temporary use NMI debugger port
as a normal console by issuing 'nmi_console' command (assuming that the
port is attached to KGDB).

Unlike KDB's disable_nmi command, with this driver you are always able
to go back to the debugger using KGDB escape sequence ($3#33).  This is
because this console driver processes the input in NMI context, and thus
is able to intercept the magic sequence.

Note that since the console interprets input and uses polling
communication methods, for things like PPP it is still better to fully
detach debugger port from the KGDB NMI (i.e. disable_nmi), and use raw
console.

Usually, to enter the debugger one have to type the magic sequence, so
initially the kernel will print the following prompt on the NMI debugger
console:

	Type $3#33 to enter the debugger>

For convenience, there is a kgdb_fiq.knock kernel command line option,
when set to 0, this turns the special command to just a return key
press, so the kernel will be printing this:

	Hit  to enter the debugger>

This is more convenient for long debugging sessions, although it makes
nmi_console feature somewhat useless.

And for the cases when NMI connected to a dedicated button, the knocking
can be disabled altogether by setting kgdb_fiq.knock to -1.

tty/serial: put (EXPERIMENTAL) marking back on N_GSM and SERIAL_IFX6X60

2012-09-18T16:17:56+00:00

Alan says these are not production ready, and users should be told this,
so put the "(EXPERIMENTAL)" marking back in the Kconfig entry string.

tty/serial: remove CONFIG_EXPERIMENTAL dependencies

2012-09-18T15:19:27+00:00

As discussed at the kernel summit this year, CONFIG_EXPERIMENTAL means
nothing, so let's get rid of it.

serial: New serial driver SCCNXP

2012-09-05T20:21:46+00:00

This driver is a replacement for a SC26XX driver with a lot of
improvements and new features.
The main differences from the SC26XX driver:
- Removed dependency on MIPS. Driver can be used on any platform.
- Added support for SCC2681, SCC2691, SCC2692, SC28L91, SC28L92,
  SC28L202, SCC68681 and SCC68692 ICs.
- Using devm_-related functions.
- Improved error handling of serial port, improved FIFO handling.
- Ability to load multiple instances of drivers.

To avoid the possibility of regression, driver SC26XX left in the
system to confirm the stability of the driver on platforms where
it is being used.

serial: New serial driver MAX310X

2012-08-16T19:12:25+00:00

This driver is a replacement for a MAX3107 driver with a lot of
improvements and new features.
The main differences from the old version:
- Using the regmap.
- Using devm_XXX-related functions.
- The use of threaded IRQ with IRQF_ONESHOT flag allows the driver to
  the hardware that supports only level IRQ.
- Improved error handling of serial port, improved FIFO handling,
  improved hardware & software flow control.
- Advanced flags allows turn on RS-485 mode (Auto direction control).
- Ability to load multiple instances of drivers.
- Added support for MAX3108.
- GPIO support.
- Driver is quite ready for adding I2C support and support other ICs
  with compatible registers set (MAX3109, MAX14830).
