* Fix version recognition in elantech_set_properties
The new hardware reports itself as v7 but the packets'
structure is unaltered.
* Fix packet type recognition in elantech_packet_check_v4
The bitmask used for v6 is too wide, only the last three bits of
the third byte in a packet (packet[3] & 0x03) are actually used to
distinguish between packet types.
Starting from v7, additional information (to be interpreted) is
stored in the remaining bits (packets[3] & 0x1c).
In addition, the value stored in (packet[0] & 0x0c) is no longer
a constant but contains additional information yet to be deciphered.
This change should be backwards compatible with v6 hardware.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.
Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.

The previous patch ("input/ti_am335x_tsc: ACK the HW_PEN irq in ISR")
acked the interrupt so we don't freeze if we don't handle an enabled
interrupt source. The interrupt core has a mechanism for this and to get
it work one should only say that it handled an interrupt if it is
actually the case.

The interrupt source IRQENB_HW_PEN is enabled in suspend and suposed to
be used as a wake up source. Once this interrupt source is unmaksed, the
devices ends up in ISR and never continues.
This change ACKs the interrupt and disables it so the system does not
freeze.

The driver programs a threshold of "coordinate_readouts" say 5. The
REG_FIFO0THR registers says it should it be programmed to "threshold
minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2.
Multiplied by two because 5 for X and 5 for Y and plus 2 because we have
two Z.
The whole thing kind of works because It reads the 5 coordinates for X
and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored
within the loop and read later.
Nothing guaranties that FIFO1 is ready by the time it is read. In fact I
could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for
Y channel 7 for Z. The problem is that channel 7 and channel 12 got
somehow mixed up.
The other Problem is that FIFO1 is also used by the IIO part leading to
wrong results if both (tsc & adc) are used.
The patch tries to clean up the whole thing a little:
- Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter
part in the for loop. This is just confusing.
- Use only FIFO0 in TSC. The fifo has space for 64 entries so should be
fine.
- Read the whole FIFO in one function and check the channel.
- in case we dawdle around, make sure we only read a multiple of our
coordinate set. On the second interrupt we will cleanup the remaining
enties.

Current code has hard coded value written to
step enable bits. Now the bits are updated based
on how many steps are needed to be configured got
from platform data.
The user needs to take care not to exceed
the count more than 16. While using ADC and TSC
one should take care to set this parameter correctly.
Sebastian added the common lock and moved the code, that manipulates the
steps, from into the mfd module.

The mfd driver creates platform data for the child devices and it is the
ti_tscadc_dev struct. This struct is copied for the two devices.
The copy of the structure makes a common lock in this structure a little
less usefull. Therefore the platform data is not a pointer to the
structure and the same structure is used.
While doing the change I noticed that the suspend/resume code assumes
the wrong pointer for ti_tscadc_dev and this has been fixed as well.

If userspace requests current KEY-state, they very likely assume that no
such events are pending in the output queue of the evdev device.
Otherwise, they will parse events which they already handled via
EVIOCGKEY(). For XKB applications this can cause irreversible keyboard
states if a modifier is locked multiple times because a CTRL-DOWN event is
handled once via EVIOCGKEY() and once from the queue via read(), even
though it should handle it only once.
Therefore, lets do the only logical thing and flush the evdev queue
atomically during this ioctl. We only flush events that are affected by
the given ioctl.
This only affects boolean events like KEY, SND, SW and LED. ABS, REL and
others are not affected as duplicate events can be handled gracefully by
user-space.
Note: This actually breaks semantics of the evdev ABI. However,
investigations showed that userspace already expects the new semantics and
we end up fixing at least all XKB applications.
All applications that are aware of this race-condition mirror the KEY
state for each open-file and detect/drop duplicate events. Hence, they do
not care whether duplicates are posted or not and work fine with this fix.
Also note that we need proper locking to guarantee atomicity and avoid
dead-locks. event_lock must be locked before queue_lock (see input-core).
However, we can safely release event_lock while flushing the queue. This
allows the input-core to proceed with pending events and only stop if it
needs our queue_lock to post new events.
This should guarantee that we don't block event-dispatching for too long
while flushing a single event queue.

"Just a 2 small driver fixups here"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: wacom - fix a typo for Cintiq 22HDT
Input: synaptics - fix sync lost after resume on some laptops
In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.
After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.
There are two PS/2 commands in psmouse_probe():
1. PSMOUSE_CMD_GETID
2. PSMOUSE_CMD_RESET_DIS
Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times. So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

Input: wacom - fix "can not retrieve extra class descriptor" for DTH2242

The trackpoint driver sets various parameter default values, all of
which happen to be power-on defaults (Source: IBM TrackPoint Engineering
Specification, Version 4.0. Also confirmed by empirical data).
By sending the power-on reset command to reset all parameters to
power-on state, we can skip the lengthy process of programming all
parameters. In testing, ~2.5 secs of time writing parameters was reduced
to .35 seconds waiting for power-on reset to complete.
