Hi, We'd like to expose the USB PD Power Source/Sink capabilities provided by a partner (SOP) to userspace. Towards that end, here is a short series which adds the capabilities to the power supply class. We also add a function to the Type C connector class to register a power supply device for a connected partner. I'm sending this out as an RFC to get some initial feedback from the relevant groups. Once we can settle on an approach, I can resend the series with a sample implementation in the Chrome OS Type C port driver (cros-ec-typec). Thanks!
