docs: Fix some broken references

2018-06-15T21:10:01+00:00

As we move stuff around, some doc references are broken. Fix some of
them via this script:
	./scripts/documentation-file-ref-check --fix

Manually checked if the produced result is valid, removing a few
false-positives.

Input: elan_i2c - add ELAN0612 (Lenovo v330 14IKB) ACPI ID

2018-06-04T20:41:49+00:00

Add ELAN0612 to the list of supported touchpads; this ID is used in Lenovo
v330 14IKB devices.

Merge branch 'next' into for-linus

2018-06-04T20:33:12+00:00

Prepare input updates for 4.18 merge window.

Merge tag 'v4.17-rc6' into next

2018-05-24T16:30:15+00:00

Sync up with mainline to bring in Atmel controller changes for Caroline.

Input: psmouse-smbus - allow to control psmouse_deactivate

2018-05-23T23:49:22+00:00

This seems to be Synaptics specific, as some Elan touchpads are not
correctly switching to SMBus if we call deactivate before switching to
SMBus on cold boot and on resume.

Tested with the T480s

Input: elantech - detect new ICs and setup Host Notify for them

2018-05-23T23:49:22+00:00

New ICs are using a different scheme for the alternate bus parameter.
Given that they are new and are only using either PS2 only or PS2 + SMBus
Host Notify, we force those new ICs to use the SMBus solution for enhanced
reporting.

This allows the touchpad found on the Lenovo T480s to report 5 fingers
every 8 ms, instead of having a limit of 2 every 8 ms.

Input: elantech - add support for SMBus devices

2018-05-23T23:49:22+00:00

Many of the Elantech devices are connected through PS/2 and a different
bus (SMBus or plain I2C).

To not break any existing device, we only enable SMBus based
on a module parameter. If some laptops require the quirk to
be set, we will have to rely on a list of PNPIds or MDI matching
to individually expose those hardware over SMBus.
the parameter mentioned above is elantech_smbus from the psmouse
module.

Input: elantech - query the resolution in query_info

2018-05-23T23:49:22+00:00

The command ETP_RESOLUTION_QUERY also contains the bus information.
It is better to fetch it once, while we are querying for device
information.

Input: elantech - split device info into a separate structure

2018-05-23T23:48:49+00:00

In preparation for SMBus device support, move static device
information that we query form the touchpad upon initialization into
separate structure. This will allow us to query the device without
allocating memory first.

Input: elan_i2c - add trackstick report

2018-05-23T23:46:36+00:00

The Elan touchpads over I2C/SMBus also can handle a trackstick.
Unfortunately, nothing tells us if the device supports trackstick (the
information lies in the PS/2 node), so rely on device properties to
determine whether to enable the trackstick node.
