    Fix wrong netmos 9855 serial port configuration.

    On loading only one serial port was present and it wasn't working. After
    looking in the data sheet I realized that the base address was wrong. For
    further reference here is lspci and relevant dmesg output:

    Currently a parport_driver can't get a handle on the device node for the
    underlying parport (PNPACPI, PCI, etc). That prevents correct placement of
    sysfs child nodes, which can affect things like power management.

    This patch adds a field to "struct parport" pointing to that device node, and
    updates non-legacy port drivers to initialize that device pointer. That field
    replaces the analagous PCI-only support in parport_pc.

  • 7a171cdcb   [SERIAL] Fix two bugs in parport_serial ... Browse Code »

    Steinar H. Gunderson reported:

    - For some reason, it detects the 9845 as a 9735 -- it appears this is
    simply related to the ordering in parport_serial_pci_tbl[]. If we move
    the 9845 up above the 9735, it prints out 9710:9845, but no change in
    behaviour. (We didn't find out why this was the case; we left it alone
    since it didn't affect our problem.)
    - The card has no parallel port (at least no physical ones), yet it reports
    (via its subsystem ID of 0x0014) one parallel port and four serial ports.
    The probe for the parallel port fails, and the driver just aborts. Thus,
    it doesn't find the serial ports.

    Fix the debugging code to use dev_dbg, but don't bother displaying the
    PCI ID of the detected board (that's accessible via other means.)

    Also, arrange for parport_register() to return 0 even if it finds no
    ports.

  • 44e58a6a0   [PATCH] parport: NetMos nm9855 fix ... Browse Code »

    kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo
    controller cards. this implementation doesn't work for nm9855 based cards!

    there are two reasons:

    a) the module 'parport_pc' doesn't want to give the resonsibility for
    the netmos_9855 to 'parport_serial' and can not handle the serial lines
    -- trivial to fix...

    http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html
    http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in

    'parport_serial' still doesn't work because of wrong assumptions about
    the relevant BARs port address layout for this chip:

    0000:00:09.0 Communication controller:
    NetMos Technology PCI 9855
    Multi-I/O Controller (rev 01)
    (= 9710:9855)
    Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014)
    Flags: medium devsel, IRQ 177
    I/O ports at a800 [size=8] (= parport)
    I/O ports at a400 [size=8]
    I/O ports at a000 [size=8] (= serial)
    I/O ports at 9800 [size=8] (= serial)
    I/O ports at 9400 [size=8] (= serial)
    I/O ports at 9000 [size=16] (= serial)

    the following patch will fix the problem.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
