iforce_get_id_packet() invokes wait_event_interruptible_timeout() which
means it has to be in non-atomic context at that point, thus we can use
GFP_KERNEL instead of GFP_ATOMIC.

The only user of this driver in mainline does not make use of the module
parameters, so let's remove them. All properties for this driver should be
set through DT or pdata.
Use touchscreen_parse_properties() to automatically set some of the common
touchscreen properties and derive the axis inversion through that.
And finally, use touchscreen_report_pos() to handle the DT properties
automatically instead of doing the inversion ourselves.

It is now only possible to control if multi-touch virtual device
is created or not (via the corresponding XenStore entries),
but keyboard and pointer devices are always created.
In some cases this is not desirable. For example, if virtual
keyboard device is exposed to Android then the latter won't
automatically show on-screen keyboard as it expects that a
physical keyboard device can be used for typing.
Utilize keyboard and pointer device XenStore feature fields to
configure which virtual devices are created:
- set "feature-disable-keyboard" to 1 if no keyboard device
needs to be created
- set "feature-disable-pointer" to 1 if no pointer device
needs to be created
Keep old behavior by default.

New ICs (like the one on the Lenovo T480s) answer to
ETP_SMBUS_IAP_VERSION_CMD 4 bytes instead of 3. This corrupts the stack
as i2c_smbus_read_block_data() uses the values returned by the i2c
device to know how many data it need to return.
i2c_smbus_read_block_data() can read up to 32 bytes (I2C_SMBUS_BLOCK_MAX)
and there is no safeguard on how many bytes are provided in the return
value. Ensure we always have enough space for any future firmware.
Also 0-initialize the values to prevent any access to uninitialized memory.

This time, Lenovo decided to go with different pieces in its latest
series of Thinkpads.
For those we have been able to test:
- the T480 is using Synaptics with an IBM trackpoint
-> it behaves properly with or without intertouch, there is no point
not using RMI4
- the X1 Carbon 6th gen is using Synaptics with an IBM trackpoint
-> the touchpad doesn't behave properly under PS/2 so we have to
switch it to RMI4 if we do not want to have disappointed users
- the X280 is using Synaptics with an ALPS trackpoint
-> the recent fixes in the trackpoint handling fixed it so upstream
now works fine with or without RMI4, and there is no point not
using RMI4
- the T480s is using an Elan touchpad, so that's a different story

trackpoints should use RMI
Lenovo use two different trackpoints in the fifth generation Thinkpad X1
Carbon. Both are accessible over SMBUS/RMI but the pnpIDs are missing.
This patch is for the Elantech trackpoint specifically which also
reports SMB version 3 so rmi_smbus needs to be updated in order to
handle it.
For the record, I was not the first one to come up with this patch as it
has been floating around the internet for a while now. However, I have
spent significant time with testing and my efforts to find the original
author of the patch have been unsuccessful.

Prevent system suspend while user has finger on touch screen,
because TSC is wakeup source and suspending device while in use will
result in failure to disable the module.
This patch uses pm_stay_awake() and pm_relax() APIs to prevent and
resume system suspend as required.

It is seen that just enabling the TSC module triggers a HW_PEN IRQ
without any interaction with touchscreen by user. This results in first
suspend/resume sequence to fail as system immediately wakes up from
suspend as soon as HW_PEN IRQ is enabled in suspend handler due to the
pending IRQ. Therefore clear all IRQs at probe and also in suspend
callback for sanity.

The current reset-gpio support triggers an interrupt storm on platforms
using the maxtouch with level based interrupt. The Motorola Droid 4,
which I used for some of the tests is not affected, since it uses a edge
based interrupt.
This change avoids the interrupt storm by enabling the device while its
interrupt is disabled. Afterwards we wait 100ms. This is important for
two reasons: The device is unresponsive for some time (~22ms for
mxt224E) and the CHG (interrupt) line is not working properly for 100ms.
We don't need to wait for any following interrupts, since the following
mxt_initialize() checks for bootloader mode anyways.
This fixes a boot issue on GE PPD (watchdog kills device due to
interrupt storm) and does not cause regression on Motorola Droid 4.

The driver needs help determining whether it is dealing with a touchscreen
or a touchpad, and with button mapping. Previously we supported passing
this data via device properties, and also had DMI lists for Chromebooks
that specified Atmel devices in ACPI, but did not provide enough data
there. Now that chromeos_laptop driver is adjusted to supply necessary
device properties even for ACPI devices, we can drop the DMI tables and
refuse to probe if device properties are not attached to the device.
We use presence of "compatible" property to determine if device properties
are attached to the device or not and rely on chromeos_laptop to re-probe
the device after attaching missing device properties to it.

Commit af503716ac14 ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.
But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).
So add compatible strings for each of the entries in the I2C device table.
Fixes: af503716ac14 ("i2c: core: report OF style module alias for devices registered via OF")

The automatic update mechanism will trigger an update if the
info block CRCs are different between maxtouch configuration
file (maxtouch.cfg) and chip.
The driver compared the CRCs without retrieving the chip CRC,
resulting always in a failure and firmware flashing action
triggered. Fix this issue by retrieving the chip info block
CRC before the check.
Note that this solution has the benefit that by reading the
information block and the object table into a contiguous region
of memory, we can verify the checksum at probe time. This means
we make sure that we are indeed talking to a chip that supports
object protocol correctly.
Using this patch on a kevin chromebook, the touchscreen and
touchpad drivers are able to match the CRC:

This patch adds the correct platform data information for the Caroline

The Samus button keymap and platform data definition are the correct
ones for Caroline, so they have been reused here.

72199320d49d ("timekeeping: Add the new CLOCK_MONOTONIC_ACTIVE clock")
As stated in the pull request for the unification of CLOCK_MONOTONIC and
CLOCK_BOOTTIME, it was clear that we might have to revert the change.
As reported by several folks systemd and other applications rely on the
documented behaviour of CLOCK_MONOTONIC on Linux and break with the above
changes. After resume daemons time out and other timeout related issues are
observed. Rafael compiled this list:
* systemd kills daemons on resume, after >WatchdogSec seconds
of suspending (Genki Sky). [Verified that that's because systemd uses
CLOCK_MONOTONIC and expects it to not include the suspend time.]
* systemd-journald misbehaves after resume:
systemd-journald[7266]: File /var/log/journal/016627c3c4784cd4812d4b7e96a34226/system.journal
corrupted or uncleanly shut down, renaming and replacing.
(Mike Galbraith).
* NetworkManager reports "networking disabled" and networking is broken
after resume 50% of the time (Pavel). [May be because of systemd.]
* MATE desktop dims the display and starts the screensaver right after
system resume (Pavel).
* Full system hang during resume (me). [May be due to systemd or NM or both.]
That happens on debian and open suse systems.
It's sad, that these problems were neither catched in -next nor by those
folks who expressed interest in this change.
