no worries, we'll get you through it :-)

actually you want to go the following route:

(1) pick up
- https://lore.kernel.org/all/20220927075511.3147847-25-clabbe@baylibre.com/
- https://lore.kernel.org/all/20220927075511.3147847-26-clabbe@baylibre.com/
as a base to work on

(2) create a patch to add your compatible.
I _think_ after that, the compatible block should looks
something like:

  compatible:
    oneOf:
      - const: rockchip,rk3288-crypto
      - const: rockchip,rk3328-crypto
      - const: rockchip,rk3399-crypto
      - items:
          - const: rockchip,rk3228-crypto
          - const: rockchip,rk3288-crypto

to handle the new dual element compatible.
	make dt_binding_check
should tell you about a wrong format.

(3) modify your dts patch to use the two compatibles
(4) export patches by
	git format-patch -2 --cover-letter
and mention in the cover-letter the dependency on the
yaml conversion.
