From: Philipp Zabel Date: Mon, 23 Feb 2015 17:40:15 +0000 (+0100) Subject: ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=40130d327f7206c76838cf8efd180d960e4ce454;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.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.
