da8065ac3e [ARM] locomo: avoid unnecessary cascaded keyboard IRQ
It is not necessary and is over-complicated for IRQ_LOCOMO_KEY to
be a cascaded IRQ of IRQ_LOCOMO_KEY_BASE. Removed and introduced
locomokbd_{open,close} for masking/unmasking of the keyboard IRQ.

633aae2 "Input: i8042 - switch to using dev_pm_ops" removed handling
for PMSG_THAW, since we do not need to do anything during freeze and
thus it was thougt that thaw is not needed as well. However, there is
a period when interrupts are kept off, and if key happens to be pressed
during that time KBC becomes jammed. To avoid the jam we simply need
to poll KBC once during thaw.

a9f0c38197 Input: psmouse - make sure we don't schedule reconnects after cleanup
Set state of the device as "initializing" during and after cleanup
to ensure that unsolicited data from the device is not passed on.
We especially want to avoid processing new device announcements
"0xaa 0x00" that can come up before we perform reconnect operation.

15e184afa8 Input: add compat support for sysfs and /proc capabilities output
Input core displays capabilities bitmasks in form of one or more longs printed
in hex form and separated by spaces. Unfortunately it does not work well
for 32-bit applications running on 64-bit kernels since applications expect
that number is "worth" only 32 bits when kernel advances by 64 bits.

Fix that by ensuring that output produced for compat tasks uses 32-bit units.

e4e6efd2df Input: psmouse - fix Synaptics detection when protocol is disabled
For configurations where Synaptics hardware is present but the Synaptics
extensions support is not compiled in, the mouse is reprobed and a new
device is allocated on every suspend/resume.

During probe, psmouse_switch_protocol() calls psmouse_extensions() with
set_properties=1. This calls the dummy synaptics_init() which returns an
error code, instructing us not to use the synaptics extensions.

During resume, psmouse_reconnect() calls psmouse_extensions() with
set_properties=0, in which case call to synaptics_init() is bypassed and
PSMOUSE_SYNAPTICS is returned. Since the result is different from previous
attempt psmouse_reconnect() fails and full re-probe happens.

Fix this by tweaking the set_properties=0 codepath in psmouse_extensions()
to be more careful about offering PSMOUSE_SYNAPTICS extensions.

30a589fde0 Input: evdev - be less aggressive about sending SIGIO notifies
When using realtime signals, we'll enqueue one signal for every event.
This is unfortunate, because (for example) keyboard presses are three
events: key, msc scancode, and syn.  They'll be enqueued fast enough in
kernel space that all three events will be ready to read by the time
userspace runs, so the first invocation of the signal handler will read
all three events, but then the second two invocations still have to run
to do no work.

Instead, only send the SIGIO notification on syn events.  This is a
slight abuse of SIGIO semantics, in principle it ought to fire as soon
as any events are readable.  But it matches evdev semantics, which is
more important since SIGIO is rather vaguely defined to begin with.

59b015133c Input: serio - fix potential deadlock when unbinding drivers
sysfs_remove_group() waits for sysfs attributes to be removed, therefore
we do not need to worry about driver-specific attributes being accessed
after driver has been detached from the device. In fact, attempts to take
serio->drv_mutex in attribute methods may lead to the following deadlock:

                                          sysfs_read_file()
                                            fill_read_buffer()
                                              sysfs_get_active_two()
                                                psmouse_attr_show_helper()
                                                  serio_pin_driver()
serio_disconnect_driver()
  mutex_lock(&serio->drv_mutex);
                                <-------->        mutex_lock(&serio_drv_mutex);
    psmouse_disconnect()
      sysfs_remove_group(... psmouse_attr_group);
        ....
        sysfs_deactivate();
          wait_for_completion();

Fix this by removing calls to serio_[un]pin_driver() and functions themselves
and using driver-private mutexes to serialize access to attribute's set()
methods that may change device state.

it introduced problems when calculating constant effects. Having 'gain'

int.

This driver was merged before the ep93xx core support was added

Now that the proper support is in the ep93xx core this driver

Summary of changes:
  1) Remove some unused members from the platform data.
  2) Remove the custom KEY macro and use the ones available in
     <linux/input/matrix_keypad.h>
  3) Remove the keypad_{readl/writel} macros and just use
     __raw_{readl/writel} directly.
  4) Update the clk_set_rate() call to work with the core support.
  5) Cleanup the probe routine and remove some unneeded messages.
  6) Use the ep93xx core functions to acquire and release the gpio's.
  7) Fix the clk_get() call to get the keypad clock.

from expresskeys for X11 driver to process them properly.
