* Input: make i2c device ids constantMárton Németh2010-01-091-1/+1
| | | | | | | | | The id_table field of the struct i2c_driver is defined as constant in <linux/i2c.h> so it makes sense to mark the initialization data also constant. Signed-off-by: Márton Németh <nm127@freemail.hu> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - check if I2C communication works during probeRichard Röjfors2009-08-041-3/+5
| | | | | | | Check the result when sending the power down command to the controller. Signed-off-by: Richard Röjfors <richard.rojfors.ext@mocean-labs.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - make get_pendown_state platform callback optionalDmitry Torokhov2009-08-041-79/+93
| | | | | | | | In cases when get_pendown_state callback is not available have the driver to fallback on pressure calculation to determine if the pen is up. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - do not read coordinates during probeRichard Röjfors2009-07-261-2/+3
| | | | | | | | Don't read coordinates during probe of the driver, just power down the controller and wait for interrupts. Signed-off-by: Richard Röjfors<richard.rojfors.ext@mocean-labs.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - make init/exit platform hw callbacks optionalRichard Röjfors2009-07-261-3/+6
| | | | | | | | Make init_platform_hw and exit_platform_hw callbacks optional since they are not needed on all platforms. Signed-off-by: Richard Röjfors <richard.rojfors.ext@mocean-labs.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - properly shut off interrupts/delayed workDmitry Torokhov2009-07-261-30/+42
| | | | | | | | | | | Properly shut off interrupts/delayed work by free-ing IRQ first and then ensuring that enable/disable is balanced. Also add __devinit/__devexit markings, restore poll delay/period scheduling logic, make sure we call exit_platform_hw() method when probe fails.

* Input: tsc2007 - remove HR timerRichard Röjfors2009-07-261-35/+13
| | | | | | | | | Since it's not allowed to do synchronous I2C in the HR timer callback context we have to switch to using the global workqueue. The work is scheduled every 1ms when polling rather than 5 us. Signed-off-by: Richard Röjfors <richard.rojfors.ext@mocean-labs.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| * Input: tsc2007 - fix locking in hrtimer handlerThierry Reding2009-05-111-2/+3
| | | | | | | | | | | | | | | | | | Now that hrtimers are always running in hard irq context we can't unconditionally enable interrupts at the end of the timer function.

* | Input: tsc2007 - make sure platform provides get_pendown_state()Kwangwoo Lee2009-05-151-1/+1
|/ | | | | | | | The platform codes must provide get_pendown_state() for the driver to work properly. Signed-off-by: Kwangwoo Lee <kwangwoo.lee@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: tsc2007 - use disable_irq_nosync() in irq handlerBen Nizette2009-04-171-1/+1
| | | | | | | | | | | 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>
