commit 40f7090bb1b4ec327ea1e1402ff5783af5b35195 upstream.

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.

commit ad8fb554f04e38f155c9bc34bbf521fc592ceee7 upstream.

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
   -&gt; 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
   -&gt; 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
   -&gt; 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

commit 5717a09aeaf62d197deba1fc7ccd6bc45f3a9dcc upstream.

Synaptics devices reported it has Intertouch support,
and it fails via PS/2 as following logs:

psmouse serio2: Failed to reset mouse on synaptics-pt/serio0
psmouse serio2: Failed to enable mouse on synaptics-pt/serio0

Set these new devices to use SMBus to fix this issue, then they report
SMBus version 3 is using, patch:
https://patchwork.kernel.org/patch/9989547/ enabled SMBus ver 3 and
makes synaptics devices work fine on SMBus mode.

<title>Input: synaptics - Lenovo Thinkpad X1 Carbon G5 (2017) with Elantech trackpoints should use RMI</title>

commit 15e2cffec3aa0d47a8d75ae80e1b136bfb5dff30 upstream.

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.

commit 9b2071028f8def49971a3b213ab6efd02a7e56e8 upstream.

The touchpad on Lenovo Carbon X1 Gen 5 (2017 - Kabylake) is accessible over
SMBUS/RMI, so let's activate it by default.

commit 567b9b549cfa1cbc202762ae97b5385c29ade1e3 upstream.

The primary interface for the touchpad device in Thinkpad L570 is SMBus,
so ALPS overlooked PS2 interface Firmware setting of TrackStick, and
shipped with TrackStick otp bit is disabled.

The address 0xD7 contains device number information, so we can identify
the device by checking this value, but to access it we need to enable
Command mode, and then re-enable the device. Devices shipped in Thinkpad
L570 report either 0x0C or 0x1D as device numbers, if we see them we assume
that the devices are DualPoints.

The same issue exists on Dell Latitude 7370.

Pull input fixes from Dmitry Torokhov:

 - we are reverting patch that was switched touchpad on Lenovo T460P
   over to native RMI because on these boxes BIOS messes up with SMBus
   controller state. We might re-enable it later once SMBus issue is
   resolved

 - disabling interrupts in matrix_keypad driver was racy

 - mms114 now has SPDX header and matching MODULE_LICENSE

This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which
caused the following issues:

1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.

The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed
rmi4_smbus 7-002c: failed to get SMBus version number!
rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.
rmi4_f01 rmi4-00.fn01: Failed to restore normal operation: -16.
rmi4_f01 rmi4-00.fn01: Resume failed with code -16.
rmi4_physical rmi4-00: Failed to suspend functions: -16
rmi4_smbus 7-002c: Failed to resume device: -16
PM: resume devices took 0.640 seconds
rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-16).
rmi4_physical rmi4-00: rmi_driver_clear_irq_bits: Failed to change enabled interrupts!
rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1

2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.

Analysis form Richard Schütz:

"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."

The affected devices often show:

i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited
