From e2b20f2d5ad6b061d7645528c45a4bfc4beb1f29 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 15 Apr 2013 19:47:40 -0700 Subject: snow: Configure the power button as an input GPIO. We need to read it to report its value to the payload. The kernel will reconfigure it as an external interrupt, but we'll make it a regular input for now.
