Hi Heikki, While testing with different type-c phones available in the market, With some phones, I noticed that supports_usb_power_delivery reports "no" eventhough an explicit pd contract has been established. After spending sometime debugging, I noticed that the root cause of this is that the partner device(acting as source) takes too long to send the SRC_CAP message. This makes the underlying TCPM code to report usb_pd set to 0 while initially calling typec_register_partner. However,since there is no provision in the type-c sysfs interface to update supports_usb_power_delivery once the contract is established, supports_usb_power_delivery is left to report "no" even if the partner source device is at present performing Type-C PD. Is it OK to add a api to enable updating supports_usb_power_delivery node in the typec sysfs code after typec_register_partner has been called ? Or do you have other suggestions ? Please advice. Thanks & Regards, Badhri. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
