2009-04-28Input: appletouch - fix DMA to/from stack bufferBob Copeland
CONFIG_DMA_API_DEBUG spotted an instance of appletouch using an array on the stack as a DMA buffer for certain hardware. Change it to use a kmalloc()ed buffer instead.

2009-04-18Input: elantech - make sure touchpad is really in absolute modeArjan Opmeer
There exist laptops with Elantech touchpads where switching to absolute mode does not happen, although writing the configuration register succeeds without error. Reading back the register afterwards reveils that the absolute mode bit is not set as if masked out by the touchpad firmware. Always read back register 0x10, make sure that for hardware version 1 the absolute mode bit is actually set and fail otherwise. This prevents the case where the touchpad is claimed by the Elantech driver but is nonetheless not working.

2009-04-18Input: elantech - provide a workaround for jumpy cursor on firmware 2.34Arjan Opmeer
It seems that Elantech touchpad firmware version 2.34 on the Hercules eCAFÉ suffers from a problem where bogus coordinates get reported at the beginning of a touch action. This causes the mouse cursor or the scrolled page to jump. Included patch provides a workaround that discards mouse packets that are likely to contain bogus coordinates. The workaround is activated when we detect touchpad with fimware version 2.34. Signed-off-by: Arjan Opmeer <arjan@opmeer.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-04-17Input: ucb1400 - use disable_irq_nosync() in irq handlerBen Nizette
disable_irq() waits 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. Signed-off-by: Ben Nizette <bn@niasdigital.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-04-15Input: ads7846 - fix unsafe disable_irqBen Nizette
The use of disable_irq inside the handler for the interrupt being disabled has always been dangerous. disable_irq should wait for that handler to complete before returning -> deadlock. For some reason this wasn't actually the case until 3aa551c9b was merged but since this time, the ads7846 driver has deadlocked the system on first interrupt. Convert the driver to use the handler-safe _nosync variant. Signed-off-by: Ben Nizette <bn@niasdigital.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

There are several DMI tables in the i8042 (keyboard) driver already, but not one for the i8042.reset option. This patch adds such an option. Two users for this table are added as well, the MSI Wind U-100 and the LG X110. The MSI Wind also needs to be in the "don't trust the pnp data" for the touchpad to work on my machine.

2009-04-11Input: i8042 - introduce a tougher resetArjan van de Ven
Some touchpads don't reset right the first time (MSI Wind U-100 for example). This patch will retry the reset up to 5 times. In addition, on x86, we don't fail entire i8042 initialization if controller reset fails in hope that keyboard port will still be functional and user will still get a working keyboard. This is especially important on netbooks. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
