The 2016 kabylake HP Spectre X360 (model number 13-w013dx) works much better with psmouse.synaptics_intertouch=1 kernel parameter, so let's enable RMI4 mode automatically.

2019-08-16Input: elantech - enable SMBus on new (2018+) systemsKai-Heng Feng1-29/+25
commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c upstream. There are some new HP laptops with Elantech touchpad that don't support multitouch. Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported, but in addition to firmware version, the bus type also informs us whether the IC can support SMBus. To avoid breaking old ICs, we will only enable SMbus support based the bus type on systems manufactured after 2018. Lastly, let's consolidate all checks into elantech_use_host_notify() and use it to determine whether to use PS/2 or SMBus.

2019-07-26Input: alps - fix a mismatch between a condition check and its commentHui Wang1-1/+1
commit 771a081e44a9baa1991ef011cc453ef425591740 upstream. In the function alps_is_cs19_trackpoint(), we check if the param[1] is in the 0x20~0x2f range, but the code we wrote for this checking is not correct: (param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f, it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f... Now fix it with a new condition checking ((param[1] & 0xf0) == 0x20).

2019-07-26Input: alps - don't handle ALPS cs19 trackpoint-only deviceHui Wang1-0/+32
commit 7e4935ccc3236751e5fe4bd6846f86e46bb2e427 upstream. On a latest Lenovo laptop, the trackpoint and 3 buttons below it don't work at all, when we move the trackpoint or press those 3 buttons, the kernel will print out: "Rejected trackstick packet from non DualPoint device" This device is identified as an alps touchpad but the packet has trackpoint format, so the alps.c drops the packet and prints out the message above. According to XiaoXiao's explanation, this device is named cs19 and is trackpoint-only device, its firmware is only for trackpoint, it is independent of touchpad and is a device completely different from DualPoint ones. To drive this device with mininal changes to the existing driver, we just let the alps driver not handle this device, then the trackpoint.c will be the driver of this device if the trackpoint driver is enabled. (if not, this device will fallback to a bare PS/2 device) With the trackpoint.c, this trackpoint and 3 buttons all work well, they have all features that the trackpoint should have, like scrolling-screen, drag-and-drop and frame-selection.

2019-07-21Input: synaptics - enable SMBUS on T480 thinkpad trackpadCole Rogers1-0/+1
commit abbe3acd7d72ab4633ade6bd24e8306b67e0add3 upstream. Thinkpad t480 laptops had some touchpad features disabled, resulting in the loss of pinch to activities in GNOME, on wayland, and other touch gestures being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids whitelist to enable the extra features. In my testing this does not break suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while also fixing the feature on a T480.

commit d21ff5d7f8c397261e095393a1a8e199934720bc upstream. 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.

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input updates from Dmitry Torokhov: - the main change is a fix for my brain-dead patch to PS/2 button reporting for some protocols that made it in 4.17 - there is a new driver for Spreadtum vibrator that I intended to send during merge window but ended up not sending the 2nd pull request. Given that this is a brand new driver we should not see regressions here - a fixup to Elantech PS/2 driver to avoid decoding errors on Thinkpad P52 - addition of few more ACPI IDs for Silead and Elan drivers - RMI4 is switched to using IRQ domain code instead of rolling its own implementation * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: psmouse - fix button reporting for basic protocols Input: xpad - fix GPD Win 2 controller name Input: elan_i2c_smbus - fix more potential stack buffer overflows Input: elan_i2c - add ELAN0618 (Lenovo v330 15IKB) ACPI ID Input: elantech - fix V4 report decoding for module with middle key Input: elantech - enable middle button of touchpads on ThinkPad P52 Input: do not assign new tracking ID when changing tool type Input: make input_report_slot_state() return boolean Input: synaptics-rmi4 - fix axis-swap behavior Input: synaptics-rmi4 - fix the error return code in rmi_probe_interrupts() Input: synaptics-rmi4 - convert irq distribution to irq_domain Input: silead - add MSSL0002 ACPI HID Input: goldfish_events - fix checkpatch warnings Input: add Spreadtrum vibrator driver
2018-06-27Input: psmouse - fix button reporting for basic protocolsDmitry Torokhov1-6/+6
The commit ba667650c568 ("Input: psmouse - clean up code") was pretty brain-dead and broke extra buttons reporting for variety of PS/2 mice: Genius, Thinkmouse and Intellimouse Explorer. We need to actually inspect the data coming from the device when reporting events.

2018-06-22Input: elan_i2c_smbus - fix more potential stack buffer overflowsBen Hutchings3-3/+11
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.

2018-05-24Input: 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.
