[PATCH 0/2] Input: tsc200x: Improve wakeup source handling

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

The tsc200x driver already uses device_init_wakeup() to read the
"wakeup-source" property from the Device Tree. However, this property
is currently not documented in the DT binding schema.

In addition, the I2C core already handles wakeup initialization and
IRQ wake management automatically when the "wakeup-source" property
is present. Therefore, the manual wakeup IRQ handling currently done
in the driver is redundant for I2C-based devices (TSC2004).

This series makes the following changes:

 1. Document the "wakeup-source" property in the DT bindings.

 2. Delegate wakeup IRQ management to the I2C core when running on
    BUS_I2C, while keeping manual management for BUS_SPI (TSC2005)
    to ensure correct behavior across both interfaces.

Note:
These changes are based on code inspection and the documented behavior
of the I2C core. They have not been tested on physical hardware yet.
