From be0e2d3e802908e2a3ca620ba8f49ecab87982b2 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Thu, 8 Oct 2009 02:03:57 -0400 Subject: [PATCH] regulator: add 88PM8607 PMIC driver Hi Liam, Since Samuel merged a new version of mfd 88pm8607 driver, I format a new patch on regulator 88pm8607. I paste the new patch in mail. Please help to review again. And I also attach the mfd driver in mail. From: Haojian Zhuang Date: Thu, 8 Oct 2009 09:36:53 -0400 Subject: [PATCH] regulator: Add 88PM8607 PMIC driver This patch adds regulator drivers for Marvell 88PM8607 PMIC. This controller contains 3 DVC and 14 LDO regulators. This controller uses I2C interface.
