The properties include cable events and the input current. The cable properties may come from different sources. Since they are associated with power_supply subsystem, it make sense to unify the properties in the power supply susbsyem layer. Also a charger can support different types of charger sources (cables). It make sense to define a field to inform the power supply subsystem what kind of cable a charger driver supports. Since a bitmask would be the easy way to do define, it's good to have a enum which has the bitmask definition for each cable types Change-Id: Ia655c0924b7a5a845121342aa8f5d3840cccfbc4 Signed-off-by: Jenny TC --- include/linux/power_supply.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) diff --git a/include/linux/power_supply.h b/include/linux/power_supply.h index ddeab05..c3ce514a 100644 --- a/include/linux/power_supply.h +++ b/include/linux/power_supply.h @@ -166,6 +166,43 @@ enum power_supply_type { POWER_SUPPLY_TYPE_USB_ACA, /* Accessory Charger Adapters */ }; +enum psy_charger_cable_event { + PSY_CHARGER_CABLE_EVENT_CONNECT = 0, + PSY_CHARGER_CABLE_EVENT_UPDATE, + PSY_CHARGER_CABLE_EVENT_RESUME, + PSY_CHARGER_CABLE_EVENT_SUSPEND, + PSY_CHARGER_CABLE_EVENT_DISCONNECT, +}; + +enum psy_charger_cable_type { + PSY_CHARGER_CABLE_TYPE_NONE = 0, + PSY_CHARGER_CABLE_TYPE_USB_SDP = 1 << 0, + PSY_CHARGER_CABLE_TYPE_USB_DCP = 1 << 1, + PSY_CHARGER_CABLE_TYPE_USB_CDP = 1 << 2, + PSY_CHARGER_CABLE_TYPE_USB_ACA = 1 << 3, + PSY_CHARGER_CABLE_TYPE_AC = 1 << 4, + PSY_CHARGER_CABLE_TYPE_ACA_DOCK = 1 << 5, + PSY_CHARGER_CABLE_TYPE_ACA_A = 1 << 6, + PSY_CHARGER_CABLE_TYPE_ACA_B = 1 << 7, + PSY_CHARGER_CABLE_TYPE_ACA_C = 1 << 8, + PSY_CHARGER_CABLE_TYPE_SE1 = 1 << 9, + PSY_CHARGER_CABLE_TYPE_MHL = 1 << 10, + PSY_CHARGER_CABLE_TYPE_B_DEVICE = 1 << 11, +}; + +struct psy_cable_props { + enum psy_charger_cable_event chrg_evt; + enum psy_charger_cable_type chrg_type; + unsigned int mA; /* input current limit */ +}; + +#define PSY_CHARGER_CABLE_TYPE_USB \ + (PSY_CHARGER_CABLE_TYPE_USB_SDP | \ + PSY_CHARGER_CABLE_TYPE_USB_DCP | \ + PSY_CHARGER_CABLE_TYPE_USB_CDP | \ + PSY_CHARGER_CABLE_TYPE_USB_ACA | \ + PSY_CHARGER_CABLE_TYPE_ACA_DOCK) + union power_supply_propval { int intval; const char *strval; @@ -181,6 +218,7 @@ struct power_supply { char **supplied_to; size_t num_supplicants; + unsigned long supported_cables; char **supplied_from; size_t num_supplies; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
