Input: elan_i2c - add another ACPI ID for Lenovo Ideapad 330-15AST

2018-08-03T05:50:21+00:00

commit 6f88a6439da5d94de334a341503bc2c7f4a7ea7f upstream. Add ELAN0622 to ACPI mapping table to support Elan touchpad found in Ideapad 330-15AST. Signed-off-by: KT Liao Reported-by: Anant Shende Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: i8042 - add Lenovo LaVie Z to the i8042 reset list

2018-08-03T05:50:20+00:00

commit 384cf4285b34e08917e3e66603382f2b0c4f6e1b upstream. The Lenovo LaVie Z laptop requires i8042 to be reset in order to consistently detect its Elantech touchpad. The nomux and kbdreset quirks are not sufficient. It's possible the other LaVie Z models from NEC require this as well.

Input: elantech - fix V4 report decoding for module with middle key

2018-07-03T09:25:04+00:00

commit e0ae2519ca004a628fa55aeef969c37edce522d3 upstream. Some touchpad has middle key and it will be indicated in bit 2 of packet[0]. We need to fix V4 formation's byte mask to prevent error decoding. Signed-off-by: KT Liao Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: elan_i2c_smbus - fix more potential stack buffer overflows

2018-07-03T09:25:04+00:00

commit 50fc7b61959af4b95fafce7fe5dd565199e0b61a upstream. 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.

Input: xpad - fix GPD Win 2 controller name

2018-07-03T09:25:03+00:00

commit dd6bee81c942c0ea01030da9356026afb88f9d18 upstream. This fixes using the controller with SDL2. SDL2 has a naive algorithm to apply the correct settings to a controller. For X-Box compatible controllers it expects that the controller name contains a variation of a 'XBOX'-string. This patch changes the identifier to contain "X-Box" as substring. Tested with Steam and C-Dogs-SDL which both detect the controller properly after adding this patch.

Input: atmel_mxt_ts - fix the firmware update

2018-06-20T19:02:52+00:00

[ Upstream commit 068bdb67ef74df0ad1627b7247a163e3e252ac11 ] The automatic update mechanism will trigger an update if the info block CRCs are different between maxtouch configuration file (maxtouch.cfg) and chip. The driver compared the CRCs without retrieving the chip CRC, resulting always in a failure and firmware flashing action triggered. Fix this issue by retrieving the chip info block CRC before the check. Note that this solution has the benefit that by reading the information block and the object table into a contiguous region of memory, we can verify the checksum at probe time. This means we make sure that we are indeed talking to a chip that supports object protocol correctly. Using this patch on a kevin chromebook, the touchscreen and touchpad drivers are able to match the CRC: atmel_mxt_ts 3-004b: Family: 164 Variant: 14 Firmware V2.3.AA Objects: 40 atmel_mxt_ts 5-004a: Family: 164 Variant: 17 Firmware V2.0.AA Objects: 31 atmel_mxt_ts 3-004b: Resetting device atmel_mxt_ts 5-004a: Resetting device atmel_mxt_ts 3-004b: Config CRC 0x573E89: OK atmel_mxt_ts 3-004b: Touchscreen size X4095Y2729 input: Atmel maXTouch Touchscreen as /devices/platform/ff130000.i2c/i2c-3/3-004b/input/input5 atmel_mxt_ts 5-004a: Config CRC 0x0AF6BA: OK atmel_mxt_ts 5-004a: Touchscreen size X1920Y1080 input: Atmel maXTouch Touchpad as /devices/platform/ff140000.i2c/i2c-5/5-004a/input/input6 Signed-off-by: Nick Dyer Acked-by: Benson Leung [Ezequiel: minor patch massage] Signed-off-by: Ezequiel Garcia Tested-by: Sebastian Reichel Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman
