Checking in if anyone has been looking at generic USB Type-C PD support?

There are obviously various ways this is dealt with in products on the market,
some uses more primitive PHY's + a big chunk of driver-code running on cpu,
some are completely standalone (proprietary / less flexible) with it's own little
cpu & binary that can operate autonomously or via a high-level serial-protocol.

Then there are parts supporting TCPC / TCPM, where the 'port-manager' runs
on the host cpu talking to the phy via (I assume) a somewhat standardized
protocol that should be generic between PD IC's supporting it.
