* HID: Multitouch support for the N-Trig touchscreenStephane Chatty2009-05-201-11/+211
| | | | | | | | | | | | | Adds support for multitouch interaction on the N-Trig touchscreen, using the new ABS_MT_* input constants. Single touch support works as previously. This code was tested against two versions of the N- Trig firmware: one that supports dual pen/finger single touch, and one that supports finger multitouch but no pen at all. Copyright notices that looked wrong were removed, as it seems that there is only code written in 2009 by Rafin Rubin and Stephane Chatty in this file.

* HID: add new multitouch and digitizer contantsStephane Chatty2009-05-202-2/+57
| | | | | | | | | | | Added constants to hid.h for all digitizer usages (including the new multitouch ones that are not yet in the official USB spec but are being pushed by Microsft as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based Computers"). Updated hid-debug.c to support the new MT input constants such as ABS_MT_POSITION_X. Signed-off-by: Stephane Chatty <chatty@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: add NOGET quirk for devices from CH ProductsAlan Stern2009-05-112-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1240) adds the NOGET quirk for three devices from CH Products: the Pro pedals, the Combatstick joystick, and the Flight-Sim yoke. Without these quirks, the devices haven't worked for many kernel releases. Sometimes replugging them after boot-up would get them to work and sometimes they wouldn't work at all.

This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination). If respective flag is not set, the driver assumes dma-unmapping as page.

| * | ipu_idmac: Use disable_irq_nosync() from within irq handlers.Ben Nizette2009-05-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | disable_irq() should wait for all running handlers to complete before returning. As such, if it's used to disable an interrupt from that interrupt's handler it will deadlock. This replaces the dangerous instances with the _nosync() variant which doesn't have this problem. Note the 2 handlers in question are only used #ifdef DEBUG so I imagine these code paths don't get hit often.

Problem is that 'gain' is passed in as signed integer. Multiplying magnitude (__u16) with gain (int) causes magnitude read as signed and results negative value (with magnitude > 0x8000). This signed integer is then divided and value, still negative, converted to 32bit unsigned integer. Finally checking combine overflow min(new+old, 0xffff) gives out 0xffff. Fix is to simply change 'gain' to unsigned int.

This usually works well but if an error occurs during configuration stage, ata_dev_revalidate_and_attach() returns with error code and forgets new_mask. On the retry run, dev->class is set and new_mask for the device is clear, so the device just gets revalidated and thus ends up skipping post-configuration procedure including scheduling of SCSI_HOTPLUG for the device. When this occurs, ATA part of probing works fine but SCSI probing usually doesn't happen and makes the device unreachable. The behavior has been around for a very long time but it has been uncovered with the recent addition of 1_5_GBPS horkage which uses -EAGAIN return value from ata_dev_configure() to restart the probing sequence after forcing cable speed. This can be fixed by making sure dev->class is permanently set only after all configurations are successfully complete. Fix it.

This patch uses a signed int for the error value so it is properly extended. Commit 6c5d0512a091480c9f981162227fdb1c9d70e555 introduced this regression.
