[PATCH v5 1/6] dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 HS phy compatible

There is a newer version of this series
[PATCH v5 1/6] dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 HS phy compatible
Posted by Pritam Manohar Sutar 2 months ago 
This SoC has USB2.0 phy and supports only UTMI+ interface. This phy
requires two clocks, named as "phy" and "ref". The required supplies for
this phy are vdd075_usb20(0.75v), vdd18_usb20(1.8v), vdd33_usb20(3.3v).

Add a dedicated compatible string for USB HS phy found in this SoC.

Presumably the existing devices don't have these new supplies, so:

Appreciated for the suggestion. Will add this change in next version (v6) of
the patch-set. 
Snippet will look as mentioned below.

+  - if:
+      properties:
+        compatible:
+          contains:
+            enum:
+              - samsung,exynosautov920-usbdrd-phy
+    then:
+      required:
+        - dvdd075-usb20-supply
+        - vdd18-usb20-supply
+        - vdd33-usb20-supply
+
+    else:
+      properties:
+        dvdd075-usb20-supply: false
+        vdd18-usb20-supply: false

Thank you.

Pritam
