* serial: only use PNP IRQ if it's validBjorn Helgaas2007-11-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | "Luming Yu" <luming.yu@gmail.com> says: There is a "ttyS1 irq is -1" problem observed on tiger4 which cause the serial port broken. It is because that there is __no__ ACPI IRQ resource assigned for the serial port. So the value of the IRQ for the port is never changed since it got initialized to -1. If PNP supplies a valid IRQ, use it. Otherwise, leave port.irq == 0, which means "no IRQ" to the serial core.

* serial: add PNP ID for Davicom ISA 33.6K modemBjorn Helgaas2007-11-141-0/+2
| | | | | | | | | | | | | | This should resolve these bug reports of the modem not working: http://bugzilla.kernel.org/show_bug.cgi?id=4355 http://www.linuxquestions.org/questions/linux-newbie-8/connect-script-failed-on-ppp-go-123975/ I don't have hardware to test this, but the initial report in the kernel bugzilla indicates that this change fixed the problem.

* Add support for Wacom WACF007 and WACF008 to serial pnp driverMaik Broemme2007-10-161-0/+2
| | | | | | | | | | | | | Notebook manufacturer seems to built a newer Wacom pen enabled tablet to recent tablet pcs which are not recognized by the serial pnp driver. Attached is a patch which makes the newer Wacom WACF007 and WACF008 tablets useable with the serial driver. The device is fully compatible with it.

* [SERIAL] add PNP IDs for FPI based touchscreensMatthew Garrett2006-10-011-0/+13
| | | | | | | | | | | | | | | | The Compaq TC1000 and Fujitsu Stylistic range of tablet machines use touchscreens from FPI. These are implemented as serial interfaces, generally exposed in the ACPIPNP information on the system. This patch adds them to the 8250_pnp driver tables, avoiding the need to mess around with setserial to set them up. I haven't been able to confirm what FUJ02B5, FUJ02BA and FUJ02BB are. FUJ02B1 refers to the controller for the system hotkeys. FUJ02BC appears to be the last in the range - after this, they moved to Wacom-based systems.

* [PATCH] SERIAL: allow shared 8250_pnp interruptsBjorn Helgaas2006-07-031-0/+2
| | | | | | | | | | | | | | | | | | | PNP devices can use shared interrupts, so check to see whether we'll need SA_SHIRQ for request_irq(). The builtin PDH UART on the HP rx8640 is an example of an ACPI/PNP device that uses a shareable level-triggered, active-low interrupt. The interrupt can be shared in very large I/O configurations or by artificially lowering IA64_DEF_LAST_DEVICE_VECTOR.

| | | | | | | | | | | | | | | | | | | Claim the WACF005 device. This is the pen display pointing device on the HP Compaq tc1100 Tablet PC. More information about using this device, including using it as an X pointer device: http://www.theory.bham.ac.uk/staff/schofield/linux/tc1100/ Christopher Kemp <ck231@cam.ac.uk> did the legwork of determining that the WACF005 is really just a plain old UART and doing an initial ACPI driver (before we had PNPACPI), and David Ludlow <dave@adsllc.com> confirmed that PNPACPI + the attached patch is now sufficient: pnp: Device 00:05 activated. ttyS4 at I/O 0x300 (irq = 4) is a 16550A Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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!
