Subject: [PATCH] rtc: rv8803: add wakeup-source support
Date: Mon, 8 Jan 2024 01:30:10 +0100 [thread overview]
Message-ID: <20240108003010.599456-1-alexandre.belloni@bootlin.com> (raw)
From: Alexandre Belloni <alexandre.belloni@bootlin.com>
The RV8803 can be wired directly to a PMIC that can wake up an SoC without
the CPU getting interrupts.
