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.
