Ping Cheng [Sat, 5 Jan 2013 07:53:52 +0000 (23:53 -0800)]
Input: wacom - prepare for syncing with input-mt changes

Henrik added new MT routines in release 3.7. This patch is to prepare
for the use of new MT routines.

In the newly added wacom_abs_set_axis() function, the first
if-statement assigns ABS_X/Y for number of contacts less or equal
to 2. So, it is single and 2 finger touch devices. Two finger touch
devices are processed here since they will not use the updated
input_mt_init_slots(), which does not offer benefit to those devices.

input_mt_init_slots() will take care of ABS_X/Y assignment when flags
are not zero. All touch devices with more than two contacts will use
input_mt_init_slots() with non-zero flags.

The second if-statement is for all MT devices, which include two
finger touch devices.

12 years agoARM - OMAP: ads7846: fix pendown debounce setting
Igor Grinberg [Wed, 21 Nov 2012 07:00:51 +0000 (23:00 -0800)]
ARM - OMAP: ads7846: fix pendown debounce setting

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

Input: introduce managed input devices (add devres support)

There is a demand from driver's writers to use managed devices framework
for their drivers. Unfortunately up to this moment input devices did not
provide support for managed devices and that lead to mixing two styles
of resource management which usually introduced more bugs, such as
manually unregistering input device but relying in devres to free
interrupt handler which (unless device is properly shut off) can cause
ISR to reference already freed memory.

This change introduces devm_input_allocate_device() that will allocate
managed instance of input device so that driver writers who prefer
using devm_* framework do not have to mix 2 styles.

kernel thread is created and all subsequent user threads are then copied from
that.  Unfortunately, however, the TBR and PSR registers are restored from the
pt_regs and the values they should be set to are clobbered by the memset.

Instead, copy across the old user registers as normal, and then merely alter
GR8 and GR9 in it if we're going to execute a kernel thread.

i2c: tegra: set irq name as device name

When watching the irqs name of tegra i2c, all instances
irq name shows as tegra_i2c.

Passing the device name properly to have the irq names with
instance like tegra-i2c.0, tegra-i2c.1 etc.

12 years agoi2c: mxs: remove broken PIOQUEUE support

i2c: mxs: remove broken PIOQUEUE support

This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.
