Subject: [PATCH v4 0/6] rockchip,otp: Support for RK3528, RK3562 and RK3568

This is a continuation of Kever's from april 2025 [0] - hence the v4
The original patches seem to have fallen through the cracks.

Additionally this directly inclues the interal word-size patch [1],
that was previously listed as an external dependency.

And finally meanwhile patches for the RK3528 SoC from Jonas have appeared,
so I've included those too, to get the support for all not-yet supported
SoCs done


Changes in v4:
- rebase onto 6.18-rc8 - the rockchip-otp driver did no receive
  additional comments in the meantime
- include the dependency patch about word-sizes
- add support for RK3528

Changes in v3:
- update the clock name from "usr" to "otp" and re-order to sync with
 other soc.
- rebase on rk3576 and rk3528, changes suggest by Jonas
- Use rk3568 data structure for rk3562

Changes in v2:
- Update the commit message and add maxItems in schema.
