Subject: [PATCH 4/6] mfd: rn5t618: wait a bit after triggering restart
Date: Thu, 11 Jun 2026 13:21:13 +0200 [thread overview]
Message-ID: <20260611112115.670073-4-l.stach@pengutronix.de> (raw)
In-Reply-To: <20260611112115.670073-1-l.stach@pengutronix.de>
The shutdown sequence performed by the PMIC after the
restart is triggered isn't instantaneous. Wait a bit
to allow the PMIC to act on our request.
