Hi!
> The twl4030 charger has two current sources, 'USB' and 'AC' (which is > really DC of course...). > > If 'AC' is providing current, we should set the current limit > differently to when it isn't (and so USB is used). > So split 'cur' into 'usb_cur' and 'ac_cur' and use accordingly. > > Now we must review the current setting on any interrupt or USB > event which might indicate that the charger-source has changed. > > Signed-off-by: NeilBrown <neilb@suse.de>
