|   | What:		/sys/kernel/debug/olpc-ec/cmd | ||
|  | Date:		Dec 2011 | ||
|  | KernelVersion:	3.4 | ||
|  | Contact:	devel@lists.laptop.org | ||
|  | Description: | ||
|  | 
 | ||
|  | A generic interface for executing OLPC Embedded Controller commands and | ||
|  | reading their responses. | ||
|  | 
 | ||
|  | To execute a command, write data with the format: CC:N A A A A | ||
|  | CC is the (hex) command, N is the count of expected reply bytes, and A A A A | ||
|  | are optional (hex) arguments. | ||
|  | 
 | ||
|  | To read the response (if any), read from the generic node after executing | ||
|  | a command. Hex reply bytes will be returned, *whether or not* they came from | ||
|  | the immediately previous command. |
