From c6c193326384aecfd668c8f271799a44dbc74c1a Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 11 Aug 2010 01:11:04 +0200 Subject: mfd: Add TPS6586x driver Add mfd core driver for TPS6586x PMICs family. The driver provides I/O access for the sub-device drivers and performs regstration of the sub-devices based on the platform requirements. In addition it implements GPIOlib interface for the chip GPIOs.
