2011-07-07x86, olpc-xo1-sci: Propagate power supply/battery eventsDaniel Drake1-0/+37
EC events indicate change in AC power connectivity, battery state of charge, battery error, battery presence, etc. Send notifications to the power supply subsystem when changes are detected.

2011-07-07x86, olpc-xo1-sci: Add GPE handler and ebook switch functionalityDaniel Drake1-1/+182
The EC in the OLPC XO-1 delivers GPE events to provide various notifications. Add the basic code for GPE/EC event processing and enable the ebook switch, which can be used as a wakeup source.

2011-07-07x86, olpc: Add XO-1 SCI driver and power button controlDaniel Drake1-0/+191
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.
