      x86, serial: convert legacy COM ports to platform devices · 7e92b4fc
      由 Bjorn Helgaas 提交于 
      Make x86 COM ports into platform devices and don't probe for them
if we have PNP.

This prevents double discovery, where a device was found both by
the legacy probe and by 8250_pnp, e.g.,

    serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
    00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

This also means IRDA devices without a UART PNP ID will no longer be
claimed by the serial driver, which might require changes in IRDA
drivers and administration.

In addition to this patch, you may need to configure a setserial init
script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART
stuff back in.  On Debian, "dpkg-reconfigure setserial" with the "kernel"
option does this.

To force the old legacy probe behavior even when we have PNPBIOS or
ACPI, load the new legacy_serial module (or build 8250 static) with
the "legacy_serial.force" option.

      [POWERPC] Open Firmware serial port driver · 8d38a5b2
      由 Arnd Bergmann 提交于 
      This can be used for serial ports that are connected to an
OF platform bus but are not autodetected by the lecacy
serial support.
It will automatically take over devices that come from the
legacy serial detection, which usually is only one device.

In some cases, rtas may be set up to use the serial port
in the firmware, which allows easier debugging before probing
the serial ports. In this case, the "used-by-rtas" property
must be set by the firmware. This patch also adds code to the
legacy serial driver to check for this.

      [ARM] 3592/1: AT91RM9200 Serial driver update · afefc415
      由 Andrew Victor 提交于 
      Patch from Andrew Victor

This patch includes a number of updates to the AT91RM9200 serial driver.

Changes include:
1. Conversion to a platform_driver.  [Ivan Kokshaysky]
2. Replaced all references to AT91RM9200 with AT91.  This driver can now
also be used for the AT91SAM9216.
3. Allow TIOCM_LOOP to configure local loopback mode.
4. Cleaned up the 'read_status_mask' usage and interrupt handler code.
[Chip Coldwell]
5. Suspend/resume support.  [David Brownell]

There are a few 'unused variable' warning when compiling this - I
removed the new DMA support to keep this first patch simpler.

      [PATCH] Altix: ioc3 serial support · 2d0cfb52
      由 Patrick Gefre 提交于 
      Add driver support for a 2 port PCI IOC3-based serial card on Altix boxes:

This is a re-submission.  On the original submission I was asked to
organize the code so that the MIPS ioc3 ethernet and serial parts could be
used with this driver.  Stanislaw Skowronek was kind enough to provide the
shim layer for this - thanks Stanislaw.  This patch includes the shim layer
and the Altix PCI ioc3 serial driver.  The MIPS merged ioc3 ethernet and
serial support is forthcoming.

      [SERIAL] Make the number of UARTs registered configurable. · a61c2d78
      由 Dave Jones 提交于 
      Also add a nr_uarts module option to the 8250 code to override
this, up to a maximum of CONFIG_SERIAL_8250_NR_UARTS

This should appease people who complain about a proliferation
of /dev/ttyS & /sysfs nodes whilst at the same time allowing
a single kernel image to support the rarer occasions of
lots of devices.
