HID: i2c-hid: override HID descriptors for certain devices A particular touchpad (SIPODEV SP1064) refuses to supply the HID descriptors. This patch provides the framework for overriding these descriptors based on DMI data. It also includes the descriptors for said touchpad, which were extracted by listening to the traffic of the windows filter driver, as well as the DMI data for the laptops known to use this device.

HID: multitouch: Add quirks for flipped axes Certain touchscreen devices, such as the ELAN9034, are oriented incorrectly and report touches on opposite points on the X and Y axes. For example, a 100x200 screen touched at (10,20) would report (90, 180) and vice versa. This is fixed by adding device quirks to transform the touch points into the correct spaces, from X -> MAX(X) - X, and Y -> MAX(Y) - Y.

HID: i2c-hid: override HID descriptors for certain devices A particular touchpad (SIPODEV SP1064) refuses to supply the HID descriptors. This patch provides the framework for overriding these descriptors based on DMI data. It also includes the descriptors for said touchpad, which were extracted by listening to the traffic of the windows filter driver, as well as the DMI data for the laptops known to use this device.

i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array Commit 9ee3e06610fd ("HID: i2c-hid: override HID descriptors for certain devices") added a new dmi_system_id quirk table to override certain HID report descriptors for some systems that lack them. But the table wasn't properly terminated, causing the dmi matching to walk off into la-la-land, and starting to treat random data as dmi descriptor pointers, causing boot-time oopses if you were at all unlucky. Terminate the array. We really should have some way to just statically check that arrays that should be terminated by an empty entry actually are so. But the HID people really should have caught this themselves, rather than have me deal with an oops during the merge window. Tssk, tssk.

HID: multitouch: Add quirks for flipped axes Certain touchscreen devices, such as the ELAN9034, are oriented incorrectly and report touches on opposite points on the X and Y axes. For example, a 100x200 screen touched at (10,20) would report (90, 180) and vice versa.
