From e1c7481797542f4d2039d5a458ef80603298ad78 Mon Sep 17 00:00:00 2001 From: "Chew, Chiau Ee" Date: Wed, 19 Feb 2014 02:24:29 +0800 Subject: ACPI / LPSS: Add Intel BayTrail ACPI mode PWM Intel BayTrail LPSS consists of two PWM controllers which can be enumerated from ACPI namespace. This change will cause platform device objects to be created for Intel BayTrail PWM controllers which will allow the pwm-lpss driver to bind to them and handle those devices.

This caused ACPI shutdown regression on gentoo in VirtualBox. Now ACPI events are sent to userspace via netlink, so add ACPI Button event back via netlink routine.
