* Input: rotary_encoder - add support for REL_* axesH Hartley Sweeten2009-04-17
| | | | | | | | | | | | | | The rotary encoder driver only supports returning input events for ABS_* axes, this adds support for REL_* axes. The relative axis input event is reported as -1 for each counter-clockwise step and +1 for each clockwise step. The ability to clamp the position of ABS_* axes between 0 and a maximum of "steps" has also been added.

* Input: ads7846 - fix unsafe disable_irqBen Nizette2009-04-15
| | | | | | | | | | | | | | | 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>

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.

* Input: add driver for S1 button of rb532Phil Sutter2009-03-09
| | | | | | | | | | | | | | | | | | | Mikrotik's Routerboard 532 has two builtin buttons, from which one triggers a hardware reset. The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: hilkbd - fix crash when removing hilkbd moduleHelge Deller2009-03-08
| | | | | | | | | | | | | | | | | | On parisc machines, which don't have HIL, removing the hilkbd module panics the kernel. Fix this by adding proper implementations for the probe and remove functions to the parisc_driver structure. A few functions were renamed to clean up the code and make it easier readable. Disable the MODULE_DEVICE_TABLE() macro on parisc since the kernel module autoloader should instead prefer the hp_sdc driver which takes care of full HIL support, including HIL mouse and HIL tablets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the mandatory algorithm testing at registration, we have now created a deadlock with algorithms requiring fallbacks. This can happen if the module containing the algorithm requiring fallback is loaded first, without the fallback module being loaded first. The system will then try to test the new algorithm, find that it needs to load a fallback, and then try to load that. As both algorithms share the same module alias, it can attempt to load the original algorithm again and block indefinitely. As algorithms requiring fallbacks are a special case, we can fix this by giving them a different module alias than the rest. Then it's just a matter of using the right aliases according to what algorithms we're trying to find. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
