Input: elan_i2c - remove Lenovo Legion Y7000 PnpID

2019-09-21T05:18:02+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.

Input: hyperv-keyboard: Use in-place iterator API in the channel callback

2019-09-10T09:35:20+00:00

[ Upstream commit d09bc83640d524b8467a660db7b1d15e6562a1de ] Simplify the ring buffer handling with the in-place API. Also avoid the dynamic allocation and the memory leak in the channel callback function. Signed-off-by: Dexuan Cui Acked-by: Dmitry Torokhov Signed-off-by: Sasha Levin

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

2019-09-06T10:42:01+00:00

This reverts commit 60956b018bfe23b879405a7d88103d0a8f06a5e3 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

2019-08-16T08:10:54+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

2019-07-26T07:10:53+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).
