| |
These patches make a number of improvements to twl4030_charger.
So are just internal cleanups (e.g. use of devres). Others allow better control of charging through both manual and automatic means.
- the maximum current can be configured via sysfs. - the charger will only draw that current if it can do so without the voltage dropping too much - a 'continuous' mode is available which ignores voltage and just takes what it can (to be used with caution, but very useful in some circumstances). - 'ac' and 'usb' power sources can be configured separately.
Some of this functionality requires patch to phy-twl4030-usb.c which have been sent separately.
Thanks, NeilBrown

NeilBrown (15): power_supply core: support use of devres to register/unregister a power supply. twl4030_charger: use devm_request_threaded_irq twl4030_charger: use devres for power_supply_register and kzalloc. twl4030_charger: use runtime_pm to keep usb phy active while charging. twl4030_charger: trust phy to determine when USB power is available. twl4030_charger: split uA calculation into a function. twl4030_charger: allow fine control of charger current. twl4030_charger: distinguish between USB current and 'AC' current twl4030_charger: allow max_current to be managed via sysfs. twl4030_charger: only draw USB current as negotiated with host. twl4030_charger: enable manual enable/disable of usb charging. twl4030_charger: add software controlled linear charging mode. twl4030_charger: add ac/mode to match usb/mode twl4030_charger: Increase current carefully while watching voltage. twl4030_charger: assume a 'charger' can supply maximum current.
