Filename should match compatibles and they do not use 28lp.
Sure. will remove the 28lp. added it based on the file name.
Is "qcom,uniphy-pcie.yaml" good ? Because this will be used for other SoCs as well which will have different compatibles. So i did not include the SoC name, lane and speed info which i have used int he compatible names.

Driver as Linux driver? Drop. Describe the hardware instead.

Drop _clk... or even drop entire clock-names. Not needed for one entry.
Sure. Will drop "_clk" part.

+  resets:
+    maxItems: 2
+
+  reset-names:
+    items:
+      - const: phy
+      - const: phy_phy
These are absolutely terrible names. If you have third one, it would be
"phy_phy_phy"? Drop or provide something useful.
Sure. Will update.

Thanks,
Nitheesh
