Subject: [PATCH v2 2/5] dt-bindings: rtc: qcom-pm8xxx: document no-alarm flag
Date: Sun, 13 Oct 2024 01:15:27 -0400 [thread overview]
Message-ID: <20241013051859.22800-3-jonathan@marek.ca> (raw)
In-Reply-To: <20241013051859.22800-1-jonathan@marek.ca>
Qualcomm x1e80100 firmware sets the ownership of the RTC alarm to ADSP.
Thus writing to RTC alarm registers and receiving alarm interrupts is not
possible.
Add a no-alarm flag to support RTC on this platform.
