From 7feda8e9f35ebb0e9f90e03acb02280bc137f784 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sat, 25 Jun 2011 17:34:12 +0100 Subject: x86, olpc: Add XO-1 SCI driver and power button control The System Control Interrupt is used in the OLPC XO-1 to control various features of the laptop. Add the driver base and the power button functionality. This driver can't be built as a module, because functionality added in future patches means that some drivers need to know at boot-time whether SCI-based functionality is available.
