From 97a4fd2751a47189aeb181da9e5a42ed651e5c33 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 20 Aug 2014 15:36:27 -0500 Subject: [PATCH] power_button: expose raw signal assertion It's useful to expose the logic of the power button assertion according to the CONFIG active level at the hardware input. Therefore, provide power_button_signal_asserted(). BUG=chrome-os-partner:31481 BRANCH=None TEST=Benson tested this on ryu since has the button cables.
