From 22aad0011e4728a29bf3775b6f5e2f9677abd8c0 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Mon, 7 Mar 2011 23:43:11 +0800 Subject: mfd: Adopt mfd_data in 88pm860x regulator Copy 88pm860x platform data into different mfd_data structure for regulator driver. So move the identification of device node from regulator driver to mfd driver.
