From ee8076ed3e1cdd0cd1e61318386932669c90b92f Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Thu, 2 Jul 2009 09:45:18 -0400 Subject: power_supply: Add a charge_type property, and use it for olpc driver This adds a new sysfs file called 'charge_type' which displays the type of charging (unknown, n/a, trickle charge, or fast charging). This allows things like battery diagnostics to determine what the battery/EC is doing without resorting to changing the 'status' sysfs output.
