| H A D | goodix.c | bd3b8480 Mon Sep 16 18:32:24 CDT 2019 Yauhen Kharuzhy <jekhor@gmail.com> Input: goodix - add support for 9-bytes reports
Some variants of Goodix touchscreen firmwares use 9-bytes finger
report format instead of common 8-bytes format.
This report format may be present as:
struct goodix_contact_data {
uint8_t unknown1;
uint8_t track_id;
uint8_t unknown2;
uint16_t x;
uint16_t y;
uint16_t w;
}__attribute__((packed));
Add support for such format and use it for Lenovo Yoga Book notebook
(which uses a Goodix touchpad as a touch keyboard).
