From mboxrd@z Thu Jan 1 00:00:00 1970 From: p.zabel@pengutronix.de (Philipp Zabel) Date: Tue, 11 Feb 2014 14:27:10 +0100 Subject: [RFC PATCH 3/4] ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay In-Reply-To: <1392125231-28387-1-git-send-email-p.zabel@pengutronix.de> References: <1392125231-28387-1-git-send-email-p.zabel@pengutronix.de> Message-ID: <1392125231-28387-4-git-send-email-p.zabel@pengutronix.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
