The interfaces are similar to the existing power supply get/set interfaces, but introduce a different set of properties in order to differentiate itself from other power supply properties which exposed in sysfs Signed-off-by: Jenny TC --- include/linux/power_supply.h | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/include/linux/power_supply.h b/include/linux/power_supply.h index 30145d8e..a80a3ef 100644 --- a/include/linux/power_supply.h +++ b/include/linux/power_supply.h @@ -176,6 +176,32 @@ union power_supply_propval { struct device; struct device_node; +enum psy_charger_control_property { + PSY_CHARGER_PROP_ENABLE_CHARGING = 0, + PSY_CHARGER_PROP_ENABLE_CHARGER, + PSY_CHARGER_PROP_RESET_WDT, +}; + +/** + * struct power_supply_charger - power supply charger driver + * @get_property: get property function to retrieve charger properties defined + * in enum power_supply_charger_property + * @set_property: get property function to retrieve charger properties defined + * in enum power_supply_charger_property + * + * This structure is used by charger drivers to register with power supply + * charging driver + */ + +struct power_supply_charger { + int (*get_property)(struct power_supply_charger *psyc, + enum psy_charger_control_property pspc, + union power_supply_propval *val); + int (*set_property)(struct power_supply_charger *psyc, + enum psy_charger_control_property pspc, + const union power_supply_propval *val); +}; + struct power_supply { const char *name; enum power_supply_type type; @@ -200,6 +226,8 @@ struct power_supply { void (*external_power_changed)(struct power_supply *psy); void (*set_charged)(struct power_supply *psy); + struct power_supply_charger *psy_charger; + /* * Set if thermal zone should not be created for this power supply. * For example for virtual supplies forwarding calls to actual -- 1.7.9.5
