usb: pd: Exposing the Peak Current value of Fixed Supplies to user spaceExposing the value of the field as is.The Peak Current value has to be interpreted as describedin Table 6-10 (Fixed Power Source Peak Current Capability)of the USB Power Delivery Specification, but thatinterpretation will be done in user space, not in kernel.Suggested-by: Douglas Gilbert Reviewed-by: Guenter Roeck Signed-off-by: Heikki Krogerus Link: https://lore.kernel.org/r/20231002142240.2641962-1-heikki.krogerus@linux.intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-usb_power_delivery

c620f4d5 - usb: typec: pd: Add higher capability sysfs for sink PDO

Tue, 14 Feb 2023 11:45:43 +0000

usb: typec: pd: Add higher capability sysfs for sink PDO28th bit of fixed supply sink PDO represents higher capability.When this bit is set, the sink device needs more than vsafe5V(eg: 12 V) to provide full functionality. This patch addsthis higher capability sysfs interface for sink PDO.28th bit of fixed supply source PDO represents usb_suspend_supportedattribute. This usb_suspend_supported sysfs is already exposed forsource PDOs. This patch adds 'source-capabilities' inusb_suspend_supported sysfs documentation for additional clarity.Signed-off-by: Saranya Gopal Reviewed-by: Heikki Krogerus Link: https://lore.kernel.org/r/20230214114543.205103-2-saranya.gopal@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-usb_power_delivery

662a6010 - usb: typec: Separate USB Power Delivery from USB Type-C

Mon, 02 May 2022 13:20:56 +0000

usb: typec: Separate USB Power Delivery from USB Type-CIntroducing a small device class for USB Power Delivery.The idea with it is that we do not mix any more USB PowerDelivery information into the USB Type-C connectors only.This separation will make it possible to register USB PowerDelivery devices also from other places, for example fromUSB Type-C Bridges (see USB Type-C Bridge Specification).The device class will not always deal with only the messagesand objects that were negotiated with the partner, butinstead messages and objects that can be used in thenegotiation. That allows the USB PD devices to be shared andreconfigured. The ports can decide which objects are to beadvertised to the partner before the contract is negotiated.It is also possible to allow the user space to make thatdecision if needed.Signed-off-by: Heikki Krogerus Link: https://lore.kernel.org/r/20220502132058.86236-2-heikki.krogerus@linux.intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-usb_power_delivery
