The maXTouch chips use the CHG line to generate status events in bootloader
mode, and during configuration download, before there is enough information
to configure the input device. Therefore set up the interrupt handler
earlier.
However, this introduces states where parts of the interrupt processing
must not run. Use data->object_table as a way to tell whether the chip
information is valid, and data->input_dev as a way to tell whether it is
valid to generate input report.

This ioctl is the counterpart to EVIOCGVERSION and returns the
uinput-version the kernel was compiled with.

This moves basic checks and setup from uinput_setup_device() into
uinput_validate_absbits() to make it easier to use. This way, we can call
it from other places without copying the boilerplate code.

It's possible that the controller has an individually switchable power supply.
Therefore add support to control a supplying regulator.
As this is not always the case, the regulator is requested as optional.

Recent version of xf86-input-wacom no longer support directly accessing
serial tablets. Instead xf86-input-wacom now expects all wacom tablets to
be driven by the kernel and to show up as evdev devices.
This has caused old serial Wacom tablets to stop working for people who still
have such tablets. Julian Squires has written a serio input driver to fix this:
https://github.com/tokenrove/wacom-serial-iv
This is a cleaned up version of this driver with improved Graphire support
(I own an old Graphire myself).

This patch introduces the use of managed interfaces like devm_kzalloc,
devm_input_allocate_device, devm_request_threaded_irq etc. and does away
with the calls to free the allocated memory. The remove function is no
longer required and is completely done away with. Also, the labels in the
probe function are removed.

This patch adds a driver for Microchips CAP1106, an I2C driven, 6-channel
capacitive touch sensor.
For now, only the capacitive buttons are supported, and no specific
settings that can be tweaked for individual channels, except for the
device-wide sensitivity gain. The defaults seem to work just fine out of
the box, so I'll leave configurable parameters for someone who's in need
of them and who can actually measure the impact. All registers are
prepared, however. Many of them are just not used for now.
The implementation does not make any attempt to be compatible to platform
data driven boards, but fully depends on CONFIG_OF.
Power management functions are also left for volounteers with the ability
to actually test them.

If we receive EC interrupts after the cros_ec driver has probed, but
before the cros_ec_keyb driver has probed, the cros_ec IRQ handler
will not run the cros_ec_keyb notifier and the EC will leave the IRQ
line asserted. The cros_ec IRQ handler then returns IRQ_HANDLED and
the resulting flood of interrupts causes the machine to hang.
Since the EC interrupt is currently only used for the keyboard, move
the setup and handling of the EC interrupt to the cros_ec_keyb driver.

2) Allow seeks on /dev/mdesc, from Khalid Aziz.
3) Cleanup sparc64 I/O accessors, from Sam Ravnborg.
4) If update_mmu_cache{,_pmd}() is called with an not-valid mapping, do
not insert it into the TLB miss hash tables otherwise we'll
livelock. Based upon work by Christopher Alexander Tobias Schulze.
5) Fix BREAK detection in sunsab driver when no actual characters are
pending, from Christopher Alexander Tobias Schulze.
6) Because we have modules --> openfirmware --> vmalloc ordering of
virtual memory, the lazy VMAP TLB flusher can cons up an invocation
of flush_tlb_kernel_range() that covers the openfirmware address
range. Unfortunately this will flush out the firmware's locked TLB
mapping which causes all kinds of trouble. Just split up the flush
request if this happens, but in the long term the lazy VMAP flusher
should probably be made a little bit smarter.
Based upon work by Christopher Alexander Tobias Schulze.

The memory are mapped using of_ioremap() which is
an indication this is sbus memory.
Shift all uses of inb/outb to the sbus variants.
The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L,
whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E.
The difference is if the reads/writes are done in
native or little endian.
But for byte reads/writes there is no difference
so this does not matter for inb/outb - and this
driver only uses the byte variants.

Pull timer and time updates from Thomas Gleixner:
"A rather large update of timers, timekeeping & co
- Core timekeeping code is year-2038 safe now for 32bit machines.
Now we just need to fix all in kernel users and the gazillion of
user space interfaces which rely on timespec/timeval :)
- Better cache layout for the timekeeping internal data structures.
- Proper nanosecond based interfaces for in kernel users.
- Tree wide cleanup of code which wants nanoseconds but does hoops
and loops to convert back and forth from timespecs. Some of it
definitely belongs into the ugly code museum.
- Consolidation of the timekeeping interface zoo.
- A fast NMI safe accessor to clock monotonic for tracing. This is a
long standing request to support correlated user/kernel space
traces. With proper NTP frequency correction it's also suitable
for correlation of traces accross separate machines.
- Checkpoint/restart support for timerfd.
- A few NOHZ[_FULL] improvements in the [hr]timer code.
- Code move from kernel to kernel/time of all time* related code.
- New clocksource/event drivers from the ARM universe. I'm really
impressed that despite an architected timer in the newer chips SoC
manufacturers insist on inventing new and differently broken SoC
specific timers.
[ Ed. "Impressed"? I don't think that word means what you think it means ]
- Another round of code move from arch to drivers. Looks like most
of the legacy mess in ARM regarding timers is sorted out except for
a few obnoxious strongholds.
- The usual updates and fixlets all over the place"

Convert the monotonic timestamp with ktime_mono_to_real() in
evdev_events().
In evdev_queue_syn_dropped() we can call either ktime_get() or
ktime_get_real() depending on the clkid. No point in having two calls
for CLOCK_REALTIME.

In the hopes that people run new kernels on their devices, let's add a
warning message asking users to have their DTS file fixed.
The goal is that by Linux 4.0 we will be able to remove support for the
bogus version of our touchscreen's DTS.

Historically we dealt with touch_max equals to 2 differently from
other MT devices. Now we use input_mt_*() to process all MT events,
as long as touch_max is greater than 1. So, there is no need to
take (touch_max == 2) as a special case any more.

The touchpad on the GIGABYTE U2442 not only stops communicating when we try
to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS
versions also when we set bit 1 (enable two finger mode auto correct).
I've asked the original reporter of:
https://bugzilla.kernel.org/show_bug.cgi?id=61151
To check that not setting bit 1 does not lead to any adverse effects on his
model / BIOS revision, and it does not, so this commit fixes the touchpad
not working on these versions by simply never setting bit 1 for laptop
models with the no_hw_res quirk.

At least the Dell Vostro 5470 elantech *clickpad* reports right button
clicks when clicked in the right bottom area:
https://bugzilla.redhat.com/show_bug.cgi?id=1103528
This is different from how (elantech) clickpads normally operate, normally
no matter where the user clicks on the pad the pad always reports a left
button event, since there is only 1 hardware button beneath the path.
It looks like Dell has put 2 buttons under the pad, one under each bottom
corner, causing this.
Since this however still clearly is a real clickpad hardware-wise, we still
want to report it as such to userspace, so that things like finger movement
in the bottom area can be properly ignored as it should be on clickpads.
So deal with this weirdness by simply mapping a right click to a left click
on elantech clickpads. As an added advantage this is something which we can
simply do on all elantech clickpads, so no need to add special quirks for
this weird model.

Add common DT binding documentation for touchscreen devices and
implement input_parse_touchscreen_of_params, which parses the common
properties and configures the input device accordingly.
The method currently does not interpret the axis inversion properties,
since there is no matching flag in the generic linux input device.
