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.

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.

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.

Certain devices implement triggers as buttons rather than axes. In
particular, arcade sticks such as the HORI Real Arcade Pro.EX do not
have analog buttons.
These devices are now setup to present buttons rather than axes for
triggers.
User-space applications often also have problems with
axes-as-buttons. Activating MAP_TRIGGERS_TO_BUTTONS for a device
removes the artificial difference between buttons and triggers.

On certain boards not all GPIOs may be used as wakeup sources, in which
case some of enable_irq_wake() calls will fail. On resume calling
disable_irq_wake() will warn about unbalanced IRQ wake disable.
Solve this by checking whether enable_irq_wake() succeeded or not and
no not call disable_irq_wake() for these GPIOs/IRQs that have not been
enabled.

The commit 9e68177ef93b2f34eee5a1e1707bceef4b9ba69c changed 'gain' from
signed to unsigned to fix an issue with rumble effect calculation, however
it introduced problems when calculating constant effects. Having 'gain'
being unsigned int was an unfortunate choice since it dominates all
implicit type conversions causing everything to be treated as unsigned
int.
Let's change it back to signed int and simply add proper casts to rumble
effect calculations.

We used to make kseriod freezable to prevent unnecessary attempts at
resuming keyboard and mouse before taking hibernation image when suspend
and hibernation were sharing PM operations. Now that they are separated
and we don't risk resuming during 'thaw' we don't need to freeze kseriod
anymore. This will allow us to start resetting mouse and keyboard a bit
earlier, before rest of the userspace comes back up.

Properly handle version of the protocol where standard PS/2 packets
from trackpoint are stuffed into middle (byte 3-6) of the standard
ALPS packets when both the touchpad and trackpoint are used together.
The patch is based on work done by Matthew Chapman and additional
research done by David Kubicek and Erik Osterholm:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/296610
Many thanks to David Kubicek for his efforts in researching fine points
of this new version of the protocol, especially interaction between pad
and stick in these models.

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.
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.
