power_supply: Add support for writeable properties
This patch adds support for writeable power supply properties and exposes them as writeable to sysfs. A power supply implementation must implement two new function calls in order to use that feature: int set_property(struct power_supply *psy, enum power_supply_property psp, const union power_supply_propval *val); int property_is_writeable(struct power_supply *psy, enum power_supply_property psp); Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Alexey Starikovskiy <astarikovskiy@suse.de> Cc: Len Brown <len.brown@intel.com> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: Matt Reimer <mreimer@vpop.net> Cc: Evgeniy Polyakov <zbr@ioremap.net> Cc: Tejun Heo <tj@kernel.org> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
