dfc1ebe766 Device tree conversions for samsung and tegra
Both platforms had some initial device tree support, but this adds
 much more to actually make it usable.
 
 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface

73db144b58 Xen: consolidate and simplify struct xenbus_driver instantiation
The 'name', 'owner', and 'mod_name' members are redundant with the
identically named fields in the 'driver' sub-structure. Rather than
switching each instance to specify these fields explicitly, introduce
a macro to simplify this.

Eliminate further redundancy by allowing the drvname argument to
DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from
the ID table will be used for .driver.name).

Also eliminate the questionable xenbus_register_{back,front}end()
wrappers - their sole remaining purpose was the checking of the
'owner' field, proper setting of which shouldn't be an issue anymore
when the macro gets used.

v2: Restore DRV_NAME for the driver name in xen-pciback.

ee9dfd7a1d Input: psmouse - make sure we do not use stale methods
Several protocol initialization routines can fail after they set up
psmouse methods, such as reconnect and disconnect. This may lead to
these stale methods used with different protocol that they were
intended to be used for and may cause unpredictavle behavior and/or
crashes.

Make sure we start with a clean slate before executing each and every
protocol detection and/or initialization routine.

If there is a full packet in the buffer, and we overflow that buffer
right after checking for that condition, it would have been possible
for us to block indefinitely (rather, until the next full packet) even if

Without this, it was possible for the reader to get ahead of packet_head.
If the input device generated a partial packet *right* after the reader
got ahead, then we can get into a situation where the device is marked
readable, but read always returns 0 until the next packet is finished
(i.e a SYN is generated by the input driver).

This situation can also happen if we overflow the buffer while a reader
is trying to read an event out.

48c98b1bb8 Input: samsung-keypad - implement runtime power management support
When runtime power management is enabled put the Samsung keypad driver
into suspend mode with wakeups disabled whenever the device is open but
a key is not actually been pressed. As well as saving a trivial amount of
power this will support the use of SoC wide idle modes which put the entire
device into a retention mode and use explicit wakeup sources to exit.

Since not all of the interrupt controllers used with the driver support
set_irq_wake() (though they all do the right thing) and there's a nasty
WARN() when we disable wake after failing to enable it keep track of the
current wake status from runtime PM and only disable wake if we managed
to enable it; I'm not entirely sure why this doesn't affect the existing
uses of the API in the driver.

System suspend is unaffected as the driver core will runtime resume any
suspended devices prior to system suspend.

Touchdata is gathered through PIXCIR Tango-ICs and processed in an
Atmel ATmega168P with custom firmware. Communication between the host
system and ATmega is done via I2C.

Devices using this touch solution include the Dell Streak5 and the family
of Qisda ebook readers.

08642e7c52 USB: convert drivers/input/* to use module_usb_driver()
This converts the drivers in drivers/input/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

83551c0159 Input: synaptics - update OLPC XO exclusion
We have determined that the jumpiness previously seen when using
the synaptics kernel mouse driver on OLPC XO was due to not using
the synaptics X11 userspace driver - the xf86-input-evdev driver was
interpreting 'finger near pad' signals as movements. Newer versions
of xf86-input-evdev fix this issue.

Additionally, the synaptics kernel driver is now usable on this
platform, but only when run in relative mode.

Update the comment and refine the check to allow the synaptics driver
to run on OLPC XO in relative mode.

We will continue investigating the EC issue as time becomes available.

7968a5dd49 Input: synaptics - add support for Relative mode
Currently, the synaptics driver puts the device into Absolute mode.
As explained in the synaptics documentation section 3.2, in this mode,
the device sends a continuous stream of packets at the maximum rate
to the host when the user's fingers are near or on the pad or
pressing buttons, and continues streaming for 1 second afterwards.
These packets are even sent when there is no new information to report,
even when they are duplicates of the previous packet.

For embedded systems this is a bit much - it results in a huge
and uninterrupted stream of interrupts at high rate.

This patch adds support for Relative mode, which can be selected as
a new psmouse protocol. In this mode, the device does not send duplicate
packets and acts like a standard PS/2 mouse. However, synaptics-specific
functionality is still available, such as the ability to set the packet
rate, and rather than disabling gestures and taps at the hardware level
unconditionally, a 'synaptics_disable_gesture' sysfs attribute has
been added to allow control of this functionality.

This solves a long standing OLPC issue: synaptics hardware enables
tap to click by default (even in the default relative mode), but we
have found this to be inappropriate for young children and first
time computer users. Enabling the synaptics driver disables tap-to-click,
but we have previously been unable to use this because it also enables
Absolute mode, which is too "spammy" for our desires and actually
overloads our EC with its continuous stream of packets. Now we can enable
the synaptics driver, disabling tap to click while retaining the less
noisy Relative mode.

Bamboo's Pen and Touch packets always start with a value

periodically sending some additional packets with unrelated data
and uses a value other than 0x02 to inform driver this.

Ignore those packets now.

This was reported by users as bad behavior in Gimp. The
invalid packets being processed made the stylus report
out of proximity for the 1 packet and this triggered some
secondary bug which caused Gimp to stop drawing until
user really took pen out of proximity of tablet.
