Input: synaptics - remove the LEN0049 dmi id from topbuttonpad list

2020-02-19T18:51:53+00:00

commit 5179a9dfa9440c1781816e2c9a183d1d2512dc61 upstream. The Yoga 11e is using LEN0049, but it doesn't have a trackstick. Thus, there is no need to create a software top buttons row. However, it seems that the device works under SMBus, so keep it as part of the smbus_pnp_ids.

Input: synaptics - switch T470s to RMI4 by default

2020-02-19T18:51:53+00:00

commit bf502391353b928e63096127e5fd8482080203f5 upstream. This supports RMI4 and everything seems to work, including the touchpad buttons. So, let's enable this by default.

Input: synaptics - switch another X1 Carbon 6 to RMI/SMbus

2019-12-13T07:52:38+00:00

commit fc1156f373e3927e0dcf06678906c367588bfdd6 upstream. Some Lenovo X1 Carbon Gen 6 laptops report LEN0091. Add this to the smbus_pnp_ids list.

Input: elan_i2c - remove Lenovo Legion Y7000 PnpID

2019-09-21T05:16:41+00:00

commit 0c043d70d04711fe6c380df9065fdc44192c49bf upstream. Looks like the Bios of the Lenovo Legion Y7000 is using ELAN061B when the actual device is supposed to be used with hid-multitouch. Remove it from the list of the supported device, hoping that no one will complain about the loss in functionality.

Revert "Input: elantech - enable SMBus on new (2018+) systems"

2019-09-06T10:40:02+00:00

This reverts commit 3d180fe5cd7625b67e0879ffa1f6ae1f09385485 which is commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c upstream. This patch depends on an other series: https://patchwork.kernel.org/project/linux-input/list/?series=122327&state=%2A&archive=both It was a mistake to backport it in the v5.2 branch, as there is a high chance we encounter a touchpad that needs the series above.

Input: synaptics - enable RMI mode for HP Spectre X360

commit 25f8c834e2a6871920cc1ca113f02fb301d007c3 upstream. 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.

Input: elantech - enable SMBus on new (2018+) systems

2019-08-16T08:12:40+00:00

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.

Input: alps - fix a mismatch between a condition check and its comment

2019-07-26T07:14:22+00:00

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).
