Subject: [PATCH] fix-pcf50633-only-do-platform-callback-once-per-event.patch
|
|
Reported-by: Holger Freyther <zecke@openmoko.org>
|
|
|
|
We harmlessly repeated PMU platform callbacks about charging state twice.
|
|
Clean it up and leave it to pcf50633_charge_enable() to report once.
|
|
|
|
Also tidies the sequencing so we set current limit before we enable
|
|
charger now.
