This adds Rockchip RK3588 AHCI binding. In order to narrow down the
allowed clocks without bloating the generic binding, the description
of Rockchip's AHCI controllers has been moved to its own file.

What about adding the "reg" property constraints? Seeing the
"ports-implemented" property is supposed to be "1" the "reg" property
should be zero for all the Rockchip AHCI SATA controllers. Right?

The "clocks" property constraints could have been added too. Right?

Please don't move the allOf property. It's ok to have it defined above
the object properties clause if it has just a few ref-statements.

* Also make sure please that the "select" property is defined above
the "allOf" schema composition.

You should be able to skip this patternProperties entirely, because it
comes from dwc-ahci-common -> ahci-common schema. Did you try the patch
without it?

Please see my message about this. The "sata-port@[0-9a-e]$" sub-node
bindings could be updated with the "reg" property constraint which,
based on the "ports-implemented" property value, most likely is
supposed to be always set to const: 1.

Then anyway the pattern is wrong as it should be @1 always.

* I miscalculated a bit, it should have been zero but in general
the pattern-property is indeed redundant.

As a conclusion the change should look like this:

+properties:
+  compatible:
+    items:
+      - enum:
+          - rockchip,rk3568-dwc-ahci
+          - rockchip,rk3588-dwc-ahci
+      - const: snps,dwc-ahci
+
+  ports-implemented:
+    const: 1
+
+  "sata-port@0":
+    $ref: /schemas/ata/snps,dwc-ahci-common.yaml#/$defs/dwc-ahci-port
+
+    properties:
+      reg:
+        const: 0
+
+    unevaluatedProperties: false
+
+ ...

Right?

Code is correct but as I said - probably meaningless. All other ports
are also accepted via referenced schema. You would need to disallow
other ports or switch to additionalProperties: false in top-level.
