From b2998049cfae4f4a81c4bb048814d34912017bb9 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Fri, 4 May 2007 00:32:17 +0400 Subject: [BATTERY] pda_power platform driver Common power driver for PDAs and phones with one or two external power supplies (AC/USB) connected to main and backup batteries, and optional builtin charger. It's used to stop logic duplication through different embedded devices. So, power supply *logic* is here. pda_power register power supplies, and will take care about notifying batteries about power changes through external power interface. Currently, power consumption legal limits (including USB power consumption) should be handled by platform code, inside set_charge function.
