dt-bindings: touchscreen: remove touchscreen.txt

2025-09-25T18:36:22+00:00

With commit 1d6204e2f51f ("dt-bindings: touchscreen: Add touchscreen schema") touchscreen.txt is no longer needed, and since no other file refers to it, it can be safely removed.

dt-bindings: input: pm8941-pwrkey: Document wakeup-source property

2025-09-25T05:43:06+00:00

The 'resin' keys (usually connected to a volume-down button) are generally not supposed to wake up the device from suspend, so explicitly document a wakeup-source property to enable this wakeup behavior. For 'pwrkey' the default stays that pressing the button does wake up the device from suspend.

Support the debounce-delay-us property. Drivers must convert this value to IPG clock cycles and map it to one of the four discrete thresholds exposed by the TSC_DEBUG_MODE2 register: 0: 8191 IPG cycles 1: 4095 IPG cycles 2: 2047 IPG cycles 3: 1023 IPG cycles Signed-off-by: Dario Binacchi Acked-by: Conor Dooley Link: https://lore.kernel.org/r/20250923143746.2857292-5-dario.binacchi@amarulasolutions.com Signed-off-by: Dmitry Torokhov

dt-bindings: touchscreen: add debounce-delay-us property

2025-09-24T21:21:00+00:00

Add support for glitch delay configuration. A detected signal is valid only if it remains stable longer than the configured delay; otherwise, it is considered a glitch. This property was introduced for the i.MX6UL touchscreen controller (TSC), which provides a hardware deglitch filter with four thresholds depending on the IPG clock frequency. In this use case, the IPG clock rate is 66 MHz, resulting in thresholds of 124 µs, 62 µs, 31 µs, and 15 µs, which requires a property with microsecond-level resolution.
