From a204f41e2d670c07c4dbd382d5bd8f6db8347ac2 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 20 Oct 2015 14:37:27 +0200 Subject: [PATCH] regulator: core: Factor out regulator_map_voltage _regulator_call_set_voltage has code to translate a minimum/maximum voltage pair into a selector. This code is useful for others aswell, so create a regulator_map_voltage function.
