From d4cc6a2eee98faebf2c7d3ebc4b35541c1d47d21 Mon Sep 17 00:00:00 2001 From: Antonio Ospite Date: Mon, 7 Dec 2009 15:08:13 +0100 Subject: leds: Add LED class driver for regulator driven LEDs. This driver provides an interface for controlling LEDs (or vibrators) connected to PMICs for which there is a regulator framework driver. This driver can be used, for instance, to control vibrator on all Motorola EZX phones using the pcap-regulator driver services.
