* | spi: use simplified spi_sync() calling conventionMarc Pignat2007-12-051-7/+6Star
|/ | | | | | | | | | | Given the patch which simplifies the spi_sync calling convention, this one updates the callers of that routine which tried using it according to the previous specification. (Most didn't.)

* Input: ads7846 - re-check pendown status before reporting eventsSemih Hazar2007-07-181-0/+15
| | | | | | | | | | | | | | Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

* Input: ads7846 - introduce sample settling delaySemih Hazar2007-07-181-1/+64
| | | | | | | | | | | | | | | The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

SPI mode 1 samples on the falling edge [2] though. The root cause of this is a bug in the omap_uwire code, which treats CPHA=1 incorrectly; so these two bugs cancel each other out on one of the main regression test platforms for this driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use hrtimer instead of the normal timer, since it provides better sampling resolution. This will: - avoid a problem where we have a 1 jiffy poll period and dynamic tick on - utilize high resolution HW clocks when they are added to the hrtimer framework Signed-off-by: Imre Deak <imre.deak@solidboot.com> Signed-off-by: Juha Yrjola <juha.yrjola@solidboot.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

|/ | | | | | | | | | | Some LCDs like the LS041Y3 require a customized filtering logic for reliable readings, so make the filtering function replacable through platform specific hooks.
