From 523d9cfbb2094e095ff08a01c4eac10cc7d287c3 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 15 Sep 2011 18:54:53 +0200 Subject: mfd: Support software initiated shutdown of WM831x PMICs In systems where there is no hardware signal from the processor to the PMIC to initiate the final power off sequence we must initiate the shutdown with a register write to the PMIC. Support such systems in the driver. Since this may prevent a full shutdown of the system platform data is used to enable the feature.
