[Mohammad Rafi Shaik]

Document compatible for Qualcomm SA8775P and QCS8300 SoC LPASS TLMM
pin controller, fully compatible with previous SM8450 generation
(same amount of pins and functions).

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

No. You are either backwards compatible with sm8450 or you aren't. The 
h/w is fixed.

ACK,

Agree,

Need backward compatibility with sm8450 for both sa8775p and qcs8300 as 
they must fall back to the sm8450, so initially used enum to pick 
between the sa8775p and qcs8300 compatibles. I see enum isn’t 
appropriate here since fixed h/w.

will use the const instead of enum like below.

  properties:
    compatible:
-    const: qcom,sm8450-lpass-lpi-pinctrl
+    oneOf:
+      - const: qcom,sm8450-lpass-lpi-pinctrl
+      - items:
+          - const: qcom,sa8775p-lpass-lpi-pinctrl
+          - const: qcom,sm8450-lpass-lpi-pinctrl
+
+      - items:
+          - const: qcom,qcs8300-lpass-lpi-pinctrl
+          - const: qcom,sm8450-lpass-lpi-pinctrl

Sigh, no. The 2 entries can be combined like you had. Just drop
minItems and maxItems from what you had.

And test your binding before sending it.
