2019-03-03Merge branch 'next' into for-linusDmitry Torokhov1-18/+4
Prepare input updates for 5.1 merge window.
2019-02-16Input: synaptics_i2c - remove redundant spinlockSven Van Asbroeck1-18/+4
Remove a leftover spinlock. This was required back when mod_delayed_work() did not exist, and had to be implemented with a cancel + queue. See commit e7c2f967445d ("workqueue: use mod_delayed_work() instead of __cancel + queue") schedule_delayed_work() and mod_delayed_work() can now be used concurrently. So the spinlock is no longer needed. Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

This reverts commit 7db54c89f0b30a101584e09d3729144e6170059d as it breaks Acer Aspire V-371 and other devices. According to Elan: "Acer Aspire F5-573G is MS Precision touchpad which should use hid multitouch driver. ELAN0501 should not be added in elan_i2c."

2019-02-07Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780Matti Kurkela1-0/+9
Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.

dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13) says it can support a different bus." I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and 4.19.x and it seems to work well. No problems seen with suspend/resume. Also, it appears that RMI/SMBus mode is actually required for 3-4 finger multitouch gestures to work -- otherwise they are not reported at all.

2018-12-21Input: elantech - disable elan-i2c for P52 and P72Benjamin Tissoires1-2/+16
The current implementation of elan_i2c is known to not support those 2 laptops. A proper fix is to tweak both elantech and elan_i2c to transmit the correct information from PS/2, which would make a bad candidate for stable. So to give us some time for fixing the root of the problem, disable elan_i2c for the devices we know are not behaving properly.

Commit 40f7090bb1b4 ("Input: elan_i2c_smbus - fix corrupted stack") fixed most of the functions using i2c_smbus_read_block_data() to allocate a buffer with the maximum block size. However three functions were left unchanged: * In elan_smbus_initialize(), increase the buffer size in the same way. * In elan_smbus_calibrate_result(), the buffer is provided by the caller (calibrate_store()), so introduce a bounce buffer. Also name the result buffer size. * In elan_smbus_get_report(), the buffer is provided by the caller but happens to be the right length. Add a compile-time assertion to ensure this remains the case.

2018-05-23Input: elantech - detect new ICs and setup Host Notify for themBenjamin Tissoires2-4/+22
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.

2018-05-23Input: elantech - add support for SMBus devicesBenjamin Tissoires6-11/+246
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.

2018-05-23Input: elantech - query the resolution in query_infoBenjamin Tissoires2-12/+17
The command ETP_RESOLUTION_QUERY also contains the bus information. It is better to fetch it once, while we are querying for device information.

2018-05-23Input: elantech - split device info into a separate structureBenjamin Tissoires2-124/+175
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.
