SubjectRe: [PATCH v2 4/8] Input: pixcir_i2c_ts: Use Type-B Multi-Touch protocol
Hi Roger,

the MT implementation seems mostly fine, just one curiosity:

> static irqreturn_t pixcir_ts_isr(int irq, void *dev_id)
> {
> struct pixcir_i2c_ts_data *tsdata = dev_id;
> const struct pixcir_ts_platform_data *pdata = tsdata->chip;
> + struct pixcir_report_data report;
>
> while (!tsdata->exiting) {
> - pixcir_ts_poscheck(tsdata);
> -
> - if (gpio_get_value(pdata->gpio_attb))
> + /* parse packet */
> + pixcir_ts_parse(tsdata, &report);
> +
> + /* report it */
> + pixcir_ts_report(tsdata, &report);
> +
> + if (gpio_get_value(pdata->gpio_attb)) {
> + if (report.num_touches) {
> + /*
> + * Last report with no finger up?
> + * Do it now then.
> + */
> + input_mt_sync_frame(tsdata->input);
> + input_sync(tsdata->input);

Why is this special handling needed?

Thanks,
Henrik
