-Subject: [PATCH] fix-bq27000-charger-state-tracking.patch
-
-Charger trigger stuff goes and asks for POWER_SUPPLY_PROP_STATUS
-to figure out what the charger state is.  But until now, we only
-reported there what we found out from HDQ, and the HDQ registers
-are not updated very often in the coulomb counter, it can be 4
-or more second lag before it tells us about what it experiences.
-
-When we react to USB insertion and only after 500ms debounce tell
-power_supply stuff that something changed, it most times will
-see old pre-USB-insertion state from bq27000 over HDQ at that time
-and will report it ain't charging, buggering up the LED trigger
-tracking.
-
-This patch maintains distance between bq27000 and pcf50633 by
-having platform callbacks in bq27000 that it can use to ask about
-definitive charger "online" presence and "activity", whether the
-charger says it is charging.  If these callbacks are implemented
-(and we implement them in this patch up in mach_gta02.c) then
-this information is used in preference to what is found from
-HDQ.
-
-Result is if you set the LED trigger like this:
-
-echo bat-charging > /sys/devices/platform/gta02-led.0/leds/gta02-aux:red/trigger
-
-then it lights up properly on USB insertion now, goes away on
-removal properly, as as far as I saw, when charging stops too.
