'serio_raw_list' and 'list' names do not accurately represent their objects and are extremely confusing when reading the code. Let's use better suited names. Reviewed-by:

CONFIG_PM is defined when CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined, however suspend and resume methods are only valid in the context of CONFIG_PM_SLEEP. If only CONFIG_PM_RUNTIME is defined we get the following warning (courtesy of Geerts randconfig builds): lm8323.c: warning: 'lm8323_resume' defined but not used Signed-off-by: -

Sysfs attribute show methods are always passed a buffer of length PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use snprintf() to guarantee we never write more than the buffer can hold. In addition, at least for my touchscreen, the number and size of objects was far too big to fit in a single 4K page. Therefore, this patch also trims some redundant framing text to leave more room for actual data. Signed-off-by:

V2 hardware has many variants. This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does. Signed-off-by:Richard Schütz <r.schtz@t-online.de> Reviewed-by:

For v2 hardware, there is no real parity check, but we can still check some constant bits for data integrity. Also rename elantech_check_parity_v1 to elantech_packet_check_v1 to make these packet checking function names consistent. Signed-off-by:

For two finger touches the coordinate of each finger gets reported separately but with reduced resolution. With this change, we now have the same range for ST and MT data and scale MT data because it has lower resolution to match ST. Suggested-by:
