From f59c8f9fe689790248ae7aa7426579982050638c Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 31 Aug 2012 10:36:37 -0700 Subject: [PATCH 01/32] regulator: core: Support bypass mode Many regulators support a bypass mode where they simply switch their input supply to the output. This is mainly used in low power retention states where power consumption is extremely low so higher voltage or less clean supplies can be used. Support this by providing ops for the drivers and a consumer API which allows the device to be put into bypass mode if all consumers enable it and the machine enables permission for this. This is not supported as a mode since the existing modes are rarely used due to fuzzy definition and mostly redundant with modern hardware which is able to respond promptly to load changes.
