      serial: New serial driver SCCNXP · 1d65c0b1
      由 Alexander Shiyan 提交于 
      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 · f6544418
      由 Alexander Shiyan 提交于 
      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).

      serial: make FSL errata depend on 8250_CONSOLE, not just 8250 · 5c2f37dd
      由 Paul Gortmaker 提交于 
      The recent commit "serial: add irq handler for Freescale 16550 errata"
would allow Kconfig choices that had 8250 support as a module and
yet still try and build in the errata fix non-modular, resulting
in build failures for some non-embedded PPC targets.

Since we hook in the errata fix from legacy_serial.c, which is
built only for PPC_UDBG_16550, and since the errata is only really
relevant for SysRQ on serial console, tighten up the dependencies
to be exactly that.

We'll get coverage on the relevant Freescale boards because the
Kconfig for their CPU types all select the PPC_UDBG_16550 option,
and the defconfigs also all select the 8250_CONSOLE option.  Also,
the 8250_CONSOLE option has a strict dependency on "SERIAL_8250=y"
which resolves the reported problem for non Freescale targets.

      serial: add irq handler for Freescale 16550 errata. · 9deaa53a
      由 Paul Gortmaker 提交于 
      Sending a break on the SOC UARTs found in some MPC83xx/85xx/86xx
chips seems to cause a short lived IRQ storm (/proc/interrupts
typically shows somewhere between 300 and 1500 events).  Unfortunately
this renders SysRQ over the serial console completely inoperable.

The suggested workaround in the errata is to read the Rx register,
wait one character period, and then read the Rx register again.
We achieve this by tracking the old LSR value, and on the subsequent
interrupt event after a break, we don't read LSR, instead we just
read the RBR again and return immediately.

The "fsl,ns16550" is used in the compatible field of the serial
device to mark UARTs known to have this issue.

Thanks to Scott Wood for providing the errata data which led to
a much cleaner fix.

      TTY: serial, move 68360 driver to staging · 3a0db721
      由 Jiri Slaby 提交于 
      This driver has been broken at least since 2008. At that time,
a88487c7 (Fix compile errors in SGI console drivers) broke this
driver completely.

And since nobody noticed for the past 3 years, move it into staging. I
think this will rot there and we will throw it away completely after
some time. Or maybe someone will volunteer to fix it ;).

So out it goes as well.

The PORT_S3C2400 definition in include/linux/serial_core.h is left there
to prevent a reuse of the same number for another port type.

      ARM: mach-s3c24a0: delete · af0e060e
      由 Nicolas Pitre 提交于 
      Commit bcae8aeb "[ARM] S3C24A0: Initial architecture support files"
brought in a bunch of files while explicitly leaving out the corresponding
Kconfig entry, stating that the series is not complete.

More than 2.5 years later, the support for this has not seen any progress.
This is therefore dead code.  If someone wants to revive this code, it is
always possible to retrieve it from the Git repository.

      SERIAL: SC26xx: Fix link error. · f2eb3cdf
      由 Ralf Baechle 提交于 
      Kconfig allows enabling console support for the SC26xx driver even when
it's configured as a module resulting in a:

ERROR: "uart_console_device" [drivers/tty/serial/sc26xx.ko] undefined!

modpost error since the driver was merged in
eea63e0e [SC26XX: New serial driver for
SC2681 uarts] in 2.6.25.  Fixed by only allowing console support to be
enabled if the driver is builtin.
