From: Philipp Zabel Date: Thu, 6 Mar 2014 09:58:48 +0000 (+0100) Subject: ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8648b2e754bbd787a9a16ee558062b4001422b82;p=karo-tx-linux.git ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay 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.
