From e843fc4616485bbd8b5a115f5bd4f73808656373 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 9 May 2012 21:16:06 +0100 Subject: regulator: core: Allow regulators to provide a voltage to selector mapping In order to allow more drivers to factor things out into data allow drivers to provide a mapping function to convert voltages into selectors. This allows any driver to use set_voltage_sel(). The existing mapping based on iterating over list_voltage() is provided as an operation which can be assigned to the new map_voltage() function though for ease of transition it is treated as the default.
