[PATCH v6 0/3] usb: typec: tipd: Add sn201202x (ACE3) support

[Sasha Finkelstein]

Add support for sn201202x (a.k.a ACE3), an Apple-specific tps6598x
variant that wraps the tps6598x core register set with a SPMI based
regmap-like protocol, first appearing in Apple M3 devices. This series
first makes the core parts bus-agnostic, and then adds the new SPMI
interface as a custom regmap implementation.

To simplify the merge strategy, the device tree entries will be sent
in a future patch series.
