Subject: [PATCH v4 5/7] ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay
Date: Tue, 18 Feb 2014 16:34:45 +0100 [thread overview]
Message-ID: <1392737687-25003-6-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1392737687-25003-1-git-send-email-p.zabel@pengutronix.de>
The PU regulator is enabled during boot, but not necessarily always-on.
It can be disabled by the generic pm domain framework when the PU power
domain is shut down. The ramp delay of 150 us might be a bit conservative,
the value is taken from the Freescale kernel.
