From 22fadd766b2a222b273df9f2264b72e4b3bbe921 Mon Sep 17 00:00:00 2001 From: Sascha Silbe Date: Fri, 10 Dec 2010 23:05:21 +0100 Subject: olpc_battery: Add support for CURRENT_NOW and VOLTAGE_NOW {CURRENT,VOLTAGE}_AVG are actually {CURRENT,VOLTAGE}_NOW (the EC code directly passes through the value from the gas gauge instead of the internally used average). We retain {CURRENT,VOLTAGE}_AVG as an alias for compatibility reasons, it will be removed later.
