Message-ID <[email protected]>
Prepare for the introduction of the Power State Change Reason Recorder
(PSCRR) framework by expanding the power_on_reason.h header. This
extension includes new power-on reasons:
- POWER_ON_REASON_OVER_CURRENT for over-current conditions.
- POWER_ON_REASON_REGULATOR_FAILURE for regulator failures.
- POWER_ON_REASON_OVER_TEMPERATURE for over temperature situations.
- POWER_ON_REASON_EC_PANIC for EC panics.
- POWER_ON_REASON_EXTERNAL for an external reset source.
