Sorry, should be the last correction for now- simplified the ofw compat bits.

It feels like this should be 2 drivers. One to talk with the ac100, and a second jsut for the rtc bits.

You never talk to the ac100, only to the rtc bits or the coded bits.
This is what DT calls MFD (Multi Function Device) and I never knew what is the best way to represent it in our drivers.

standard -> optional ac100, add ac100 to the arm/GENERIC config near rsb and axp209/axp81x.

How would an eventual codec driver interact with this one?

AFAICT, it's intended that the AC100 bits should be an all-in-one kind of driver, thus the codec driver would 'attach' like the RTC does here; not actually having its own resources or anything to that effect, and sharing a context with the RTC.

Apr 20, 2017 Users who have devices running Allwinner chipset can utilize PhoenixSuit Tool to flash system firmware on them. Be it an official update, or something from third-party developers, the PhoenixSuit allows you to modify the system partition on an Allwinner chipset device. A80, A83T are the second generation of SS. It is a two stream Crypto Accelerator with mode functions then 1st SS (SHA224/SHA256/RSA) There are handled by the sun8i-ss driver. H3, H5, H6, R40 and A64 have the third generation of SS (renamed to CE).
