Subject: Input: xilinx_ps2 - allocate serio port separately

'struct serio' is a refcounted data structure with lifetime rules different
from 'struct xps2data'. It is quite likely that serio_unregister_port() will
try to free memory allocated by the port and that is why it should be
allocated separately.

Also switch to using platform_get/set_drvdata instead of dev_get/set_drvdata
because we are dealing with platform device.

Subject: Input: add support for LM8333 keypads

This driver adds support for the keypad part of the LM8333 and is
prepared for possible GPIO/PWM drivers. Note that this is not a MFD
because you cannot disable the keypad functionality which, thus,
has to be handled by the core anyhow.

Subject: Input: wacom - add Intuos5 Touch Ring LED support

The Touch Ring LEDs on Intuos5 tablets use a different report
format which supports only 4 levels of brightness. We remap
the 7-bit value obtained from sysfs to an appropriate value
for the tablet. Control of the crop mark LEDs (new to the I5)
is left for a later patch.

Subject: Input: wacom - add Intuos5 multitouch sensor support

Intuos5 tablets with PTH-* model numbers include a multitouch sensor
which use the same touch reports as the 3rd-generation Bamboo. No
useful information is in the HID descriptor for the touch interface
so hardcoded values are used during setup.

From 98a84131926ebafe868c65631b69d4912922211e Mon Sep 17 00:00:00 2001
From: Axel Lin <axel.lin@gmail.com>
Date: Tue, 3 Apr 2012 23:52:27 -0700
Subject: Input: gameport - use module_gameport_driver

This patch converts the drivers in drivers/input/* to use
module_gameport_driver() macro which makes the code smaller
and a bit simpler.

Subject: Input: wacom_i2c - do not use irq_to_gpio

Because irq_to_gpio() is not available on many platforms let's switch
to level-triggered one-shot IRQs that will stay active as long as
there is data to be read.

Subject: Input: matrix-keypad - fix 'duplicate const' sparse warning

SIMPLE_DEV_PM_OPS already defines constant dev_pm_ops.

Also guard PM methods with CONFIG_PM_SLEEP and get rid of some
unneeded #ifdefs.

There also no need to mask out nibbles form board->krow and board->kcol

Subject: Input: serio_raw - ensure we don't block in non-blocking read

Avoid calling wait_event_interruptible() if client requested non-blocking
read, since it is not guaranteed that another thread will not consume
event after we checked if serio_raw->head != serio_raw->tail.

Also ensure we do not return 0 but keep waiting instead in blocking case,
when another thread steals "our" byte.

Subject: Input: lpc32xx_ts - fix device tree compatible string

During the device tree integration of the various LPC32xx drivers,
we agreed on using non-wildcard "compatible" strings. This change
switches lpc32xx_ts touchscreen driver to use "nxp,lpc3220-tsc".

Subject: Input: pxa27x_keypad keep clock on as wakeup source

When the keypad is used as wake up source, the clock can not
be disabled. Or it can not detect key pressing.
If the keypad is used as wake up source, when resume back,

KPDK_DK only indicates the pin level of direct key.
So it is related to board, and low level may be active which
indicates that a key is pressed.

From 1963518b9b1b8019d33b4b08deee6f873ffa2730 Mon Sep 17 00:00:00 2001
From: Ping Cheng <pinglinux@gmail.com>
Date: Sun, 29 Apr 2012 21:09:18 -0700
Subject: Input: wacom - add 0xE5 (MT device) support

Main part of patch is adding support for a new Wacom MT touch
packet and labels these devices using MTSCREEN type.

Other items of interest:

Delete some duplicate code in HID parsing for Y info since
its already done in X path.

In wacom_query_tablet_data(), only invoke the set report
that requests tablets to send Wacom Touch packets for
Finger interfaces.  Mostly, this is to make code intent clear.

Subject: Input: add support for DA9052/53 touch screen controller

This driver adds support for DA9052/53 4-wire resistive ADC interfaced
touchscreen controller. DA9052/53 is a multi-function device, therefore
this driver depends on DA9052/53 core.

This patch is functionally tested on Samsung SMDKV6410.

device.  Fix up the places where I got this wrong.

dbg() was a very old USB-specific macro that should no longer
be used. This patch removes it from being used in the driver
and uses dev_dbg() instead.

Subject: USB: usbtouchscreen.c: remove dbg() usage

dbg() was a very old USB-specific macro that should no longer
be used. This patch removes it from being used in the driver
and uses dev_dbg() instead.

Subject: Input: serio_raw - signal EFAULT even if read/write partially
 succeeds

When copy_to/from_user fails in the middle of transfer we should not
report to the user that read/write partially succeeded but rather
report -EFAULT right away, so that application will know that it got
its buffers all wrong.

If application messed up its buffers we can't trust the data fetched
from userspace and successfully written to the device or if data read
from the device and transferred to userspace ended up where application
expected it to end.

If serio_write() fails we still going to report partial writes if failure
happens in the middle of the transfer.

This is basically a revert of 7a0a27d2ce38aee19a31fee8c12095f586eed393
and 4fa0771138d0b56fe59ab8ab3b1ce9e594484362.

Subject: Input: mpu3050 - set IRQF_ONESHOT when requesting the interrupt

Commit 1c6c695 "genirq: Reject bogus threaded irq requests" requires
that request_threaded_irq() either be passed an explicit handler, or
that IRQF_ONESHOT be set. Set this flag.

Subject: Input: evdev - properly access RCU-protected 'grab' data

We should use rcu_dereference_protected() when checking if given client
is the one that grabbed the device. This fixes warnings produced by
sparse.

Subject: Input: evdev - properly handle read/write with count 0

According to the standard count 0 is special - no IO should happen but we
can check error conditions (device gone away, etc), and return 0 if there
are no errors. We used to return -EINVAL instead and we also could return 0
if an event was "stolen" by another thread.

Subject: USB: input: powermate.c: fix up dev_* messages

Previously I had made the struct device point to the input device, but
after talking with Dmitry, he said that the USB device would make more
sense for this driver to point to.  So converted it to use that instead.

Date: Mon, 7 May 2012 08:45:58 -0700
Subject: Input: sentelic - report device's production serial number

Hardware since Cx supports an unique identity (used to identify OEM vendors
and released lot number) which is very helpful for diagnostic purpose.
This revision tries to make it as a part of driver boot up message.

Whilst here, also bumping fsp_drv_ver to acknowledge recent addition of
absolute coordinates output.

atmel_mxt devices will send a checksum byte at the end of a message if
the MSB of the object address is set.
However, since this driver does not set this bit, the checksum byte
isn't actually sent, so don't even try to read it.

Subject: Input: ALPS - add semi-MT support for v4 protocol

This patch adds semi-MT support for ALPS v4 protocol touchpads.
It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
support. Three packets are required to assemble and process the MT
data. ST events are reported at once to avoid latency. If there
were two contacts or more, report MT data instead of ST events.

Thanks to Seth Forshee for providing most of the code, guidance
and insight for producing this patch.

Subject: [PATCH] Input: omap-keypad: dynamically handle register offsets

Keypad controller register offsets are different for omap4
and omap5. Handle these offsets through static mapping and
assign these mappings during run time.

Tested on omap4430 sdp with 3.4-rc3.
Tested on omap5430evm with 3.1-custom kernel.

From b45c8f35a7fec17bdd159a7815203b6137c00ab9 Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
Date: Thu, 10 May 2012 22:37:15 -0700
Subject: Input: matrix-keymap - wire up device tree support

When platform keymap is not supplied to matrix_keypad_build_keymap()
and device tree support is enabled, try locating specified property
and load keymap from it. If property name is not defined, try using
"linux,keymap".

Based on earlier patch by Viresh Kumar <viresh.kumar@st.com>

From cd99758ba3bde64347a8ece381cbae2fb5c745b2 Mon Sep 17 00:00:00 2001
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
Date: Mon, 14 May 2012 23:14:24 +0200
Subject: mfd: Convert wm831x to irq_domain

The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

Subject: Input: matrix-keymap - fix building keymaps

Keymaps used by drivers based on matrix-keymap facilities are arrays of
unsigned shorts, not chars. Treating them otherwise produces corrupted
keymaps.

Subject: i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLING

Since there are uses for I2C_M_NOSTART which are much more sensible and
standard than most of the protocol mangling functionality (the main one
being gather writes to devices where something like a register address
needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
for this feature and update all the users to use it.

Also strengthen the disrecommendation of the protocol mangling while we're
at it.

In the case of regmap-i2c we remove the requirement for mangling as
I2C_M_NOSTART is the only mangling feature which is being used.
