| | | * Input: elantech - touchpad driver miss-recognising logitech miceArjan Opmeer2009-02-281-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Logitech mice react to the magic knock like Elantech touchpad would. This leads to those mice being misdetected as Elantech touchpads. Add a version query to elantech_detect() to distinguish the two. [dtor@mail.ru: - lower severity of some messages - when we are not sure yet if device is Elantech or not not responding to knock is not an error. ] Signed-off-by: Arjan Opmeer <arjan@opmeer.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
| | | * Input: synaptics - ensure we reset the device on resumeAndy Whitcroft2009-02-281-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When resuming from suspend newer Synaptics touchpads do not recover correctly. Analysis of the resume sequence as applied in Linux was compared to that of other operating systems. This indicated that the other OSs were resetting the mouse before attempting to detect it (for all Synaptics touchpads, old and new). Applying this same modification fixes these newer Synaptics touchpads and brings the driver into line with common OS reset behaviour.

| | | * Input: usbtouchscreen - fix eGalax HID ignoringDaniel Ritz2009-02-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ec42d4481e36cbdb5b2801f957e678211a9e5ae2 broke usbtouchscreen for some eGalax/EETI devices that claim to be HID, but are not. Devices confirmed to be real HID have the class set to HID and the protocol set to 'mouse'. Some have HID class but protocol set to 'none'. Those are not HID and should be driven by usbtouchscreen. Fix the device ignoring macro by adding match for the protocol too. Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the apanel driver to the new i2c device driver binding model, as the legacy model is going away soon. In the new model, the apanel driver is no longer scanning all the i2c adapters, instead the relevant bus driver (i2c-i801) is instantiating the device as needed. One side benefit is that the apanel driver will now load automatically on all systems where it is needed.

My machine was affected as well: any speaker output hung the machine completely, nothing in the logs, no magic sysrq, etc., looked like a hardware problem. Had a closer look on the issue, and it turned out that the pcspkr module is responsible. The cause is the bad setup of Timer 2 in the i8253 controller, which probably hangs the whole PIT controller. Intel datasheets [2] state that the timer registers are in an undefined state after reset and they need to be programmed before enabling the timer. (And enabling without programming the frequency first doesn't make sense anyway). I don't know which chipsets are affected (if not all), it also depends on the BIOS whether it initializes the timer (e.g. to beep when you start the machine). The following patch solved the issue on my ICH6 notebook, couldn't test it with any others, but should be safe to apply.

| * | Input: usbtouchscreen - fix TSC-10 DM USB controllers without EEPROMNuno Lucas2008-11-191-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usbtouchscreen module implements a driver for the TSC-10 DM USB touchscreen controllers, but assumes a 2-byte response for the CMD_RESET and CMD_RATE commands, when they can be only a single byte when no EEPROM is connected. The driver worked with an earlier controller revision, but new revisions of the controller fail. It seems the problem is that the early controller had the SEL4/EEPROM-CS pin high, but the new controller has it down, making the response different. Without the fix, the controller would answer the single byte 0x06 (ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as initialized before). As the single byte is the only thing we need to check it was ok, there is no need to verify the second byte. The [0x15 0x01] case is the NAK [0x15] response for when there is no data in the EEPROM [bit-0 of second byte set], so I let that be, as I don't have any controller with an EEPROM. With this patch, both the earlier and latest controller work the same. Note: This was previously submited as BUG #11961 [1] on the bugzilla tracker, but rebased to version 2.6.27.4 and with unnecessary comments and printk's removed.
