      [SERIAL] sunsu: Handle keyboard and mouse ports directly. · 91d1ed1a
      由 David S. Miller 提交于 
      The sunsu_ports[] array exists merely to be able to easily
use an integer index to get at the proper serial console
port struct.

We size this only for real ports, not for the keyboard and
mouse, and thus keyboard and mouse port registration would
fail.

Fix this by dynamically allocating the port struct for the
keyboard and mouse, instead of using the sunsu_ports[]
array.

      [SERIAL] 8250: add tsi108 serial support · 3be91ec7
      由 Zang Roy-r61911 提交于 
      The following patch gets rid of CONFIG_TSI108_BRIDGE.  I add UPIO_TSI to
handle IIR and IER register in serial_in and serial_out.

(1) the reason to rewrite serial_in:

    TSI108 rev Z1 version ERRATA.  Reading the UART's Interrupt
    Identification Register (IIR) clears the Transmit Holding Register
    Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if they
    are not enabled in the Interrupt Enable Register (IER).  This leads to
    loss of the interrupts.  Interrupts are not cleared when reading UART
    registers as 32-bit word.

(2) the reason to rewrite serial_out:

    Check for UART_IER_UUE bit in the autoconfig routine.  This section
    of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are
    reserved for internal use.  They are R/W bits.  In addition to
    incorrect identification, changing these bits (from 00) will make
    Tsi108/109 UART non-functional.

      [SERIAL] IP22: fix serial console hangs · c65b15cf
      由 Julien BLACHE 提交于 
      The patch below fixes serial console hangs as seen on IP22
machines. Typically, while booting, the machine hangs for ~1 minute
displaying "INIT: ", then the same thing happens again when init
enters in the designated runlevel and finally the getty process on
ttyS0 hangs indefinitely (though strace'ing it helps).

strace (-e raw=ioctl, otherwise the ioctl() translation is utterly
bogus) reveals that getty hangs on ioctl() 0x540f which happens to be
TCSETSW (I saw it hang on another console ioctl() but couldn't
reproduce that one).

A diff between ip22zilog and sunzilog revealed the following
differences:
 1. the channel A flag being set on up.port.flags instead of up.flags
 2. the channel A flag being set on what is marked as being channel B
 3. sunzilog has a call to uart_update_timeout(port, termios->c_cflag, baud);
    at the end of sunzilog_set_termios(), which ip22zilog lacks (on
    purpose ?)

The patch below addresses point 1 and fixes the serial console hangs
just fine. However point 2 should be investigated by someone familiar
with the IP22 Zilog; it's probably OK as is but even if it is, a
comment in ip22zilog.c is badly needed.

Point 3 is left as an exercise for whoever feels like digging into
ip22zilog :)

These are the main obvious differences between ip22zilog and
sunzilog. Newer versions of sunzilog (Linus's git tree as of today)
are more close to ip22zilog as the sbus_{write,read}b have been
changed into simple {write,read}b, which shrinks the diff by a fair
amount. Resyncing both drivers should be doable in a few hours time
now for someone familiar with the IP22 Zilog hardware.

      [SERIAL] Ensure 8250_pci quirks are not marked __devinit · 61a116ef
      由 Russell King 提交于 
      The 8250_pci quirks must not be marked __devinit since they may
be used from parport_serial.  We only really need to mark those
which might be used by cards recognised by parport_serial, but
that wouldn't allow static checking.

      [POWERPC] Add new interrupt mapping core and change platforms to use it · 0ebfff14
      由 Benjamin Herrenschmidt 提交于 
      This adds the new irq remapper core and removes the old one.  Because
there are some fundamental conflicts with the old code, like the value
of NO_IRQ which I'm now setting to 0 (as per discussions with Linus),
etc..., this commit also changes the relevant platform and driver code
over to use the new remapper (so as not to cause difficulties later
in bisecting).

This patch removes the old pre-parsing of the open firmware interrupt
tree along with all the bogus assumptions it made to try to renumber
interrupts according to the platform. This is all to be handled by the
new code now.

For the pSeries XICS interrupt controller, a single remapper host is
created for the whole machine regardless of how many interrupt
presentation and source controllers are found, and it's set to match
any device node that isn't a 8259.  That works fine on pSeries and
avoids having to deal with some of the complexities of split source
controllers vs. presentation controllers in the pSeries device trees.

The powerpc i8259 PIC driver now always requests the legacy interrupt
range. It also has the feature of being able to match any device node
(including NULL) if passed no device node as an input. That will help
porting over platforms with broken device-trees like Pegasos who don't
have a proper interrupt tree.

      [SERIAL] Convert fifosize to an unsigned int · 947deee8
      由 Russell King 提交于 
      Some UARTs have more than 255 bytes of FIFO, which can't be
represented by an unsigned char.  Change the kernel's internal
structure to be an unsigned int, but still export an unsigned char
via the TIOCGSERIAL ioctl.  If the TIOCSSERIAL ioctl provides a
fifo size of 0, assume this means "don't change" otherwise we'll
corrupt the larger fifo sizes.
