bootloaders such as u-boot might enable regulators, or simply regulators could be enabled by default by the PMIC, even if we don't have a driver for the device or subsystem. Disable unused regulators just before going to userland. A tunable hw.regulator.disable_unused is added to not disable them in case this causes problems on some board but the default behavior is to disable everything unused. I prefer to break thinks now and fix them rather than never switch to the case were we disable regulators. Tested on : Pine64-LTS (an idle board goes from ~0.33A to ~0.27A) Tested on : BananaPi M2 Differential Revision: https://reviews.freebsd.org/D14781 |
