From 98a175b60f46a80dfa44fb0e0807f2e5a351f35f Mon Sep 17 00:00:00 2001 From: Yadwinder Singh Brar Date: Sat, 9 Jun 2012 16:40:38 +0530 Subject: regulator: core: Add regulator_set_voltage_time_sel to calculate ramp delay. This patch adds regulator_set_voltage_time_sel(), to move into core, the commonly used code by drivers to provide the .set_voltage_time_sel callback. It will also allow us to configure different ramp delay for different regulators easily.
