From 87e1e0f29f703e91c54e81f05d831432ec659dde Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 10 Nov 2014 14:43:52 +0100 Subject: [PATCH] regulator: Add mode mapping function to struct regulator_desc The "regulator-initial-mode" and "regulator-mode" DT properties allows to configure the regulator operating modes at startup or when a system enters into a susend state. But these properties use as valid values the operating modes supported by each device while the core deals with the standard operating modes. So a mapping function is needed to translate from the hardware specific modes to the standard ones. This mapping is a non-varying configuration for each regulator, so add a function pointer to struct regulator_desc that will allow drivers to define their callback to do the modes translation.
