Subject: [PATCH 2/4] regulator: add support for struct regulator_desc::off_on_delay
Date: Mon, 8 Feb 2021 20:18:25 +0100 [thread overview]
Message-ID: <20210208191827.19241-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210208191827.19241-1-a.fatoum@pengutronix.de>
We already honour the enable time in the device tree, read it out
of a new regulator_desc::off_on_delay as well, same as Linux does.
