usb: typec: constify the struct device_type usage Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move all the device_type variables in use by the driver to be constant structures as well, placing it into read-only memory which can not be modified at runtime. Signed-off-by: Ricardo B.

The Peak Current value has to be interpreted as described in Table 6-10 (Fixed Power Source Peak Current Capability) of the USB Power Delivery Specification, but that interpretation will be done in user space, not in kernel.

drivers: remove struct module * setting from struct class There is no need to manually set the owner of a struct class, as the registering function does it automatically, so remove all of the explicit settings from various drivers that did so as it is unneeded. This allows us to remove this pointer entirely from this structure going forward. Cc: "Rafael J.

usb: typec: pd: Add higher capability sysfs for sink PDO 28th 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 adds this higher capability sysfs interface for sink PDO. 28th bit of fixed supply source PDO represents usb_suspend_supported attribute. This usb_suspend_supported sysfs is already exposed for source PDOs. This patch adds 'source-capabilities' in usb_suspend_supported sysfs documentation for additional clarity.

usb: typec: Separate USB Power Delivery from USB Type-C Introducing a small device class for USB Power Delivery. The idea with it is that we do not mix any more USB Power Delivery information into the USB Type-C connectors only. This separation will make it possible to register USB Power Delivery devices also from other places, for example from USB Type-C Bridges (see USB Type-C Bridge Specification). The device class will not always deal with only the messages and objects that were negotiated with the partner, but instead messages and objects that can be used in the negotiation. That allows the USB PD devices to be shared and reconfigured. The ports can decide which objects are to be advertised to the partner before the contract is negotiated. It is also possible to allow the user space to make that decision if needed.
