Any particular reason to use different BSD-3 than bindings? Not easy to
spot this difference...

Best regards,

Not really, I can change it to BSD-2 if needed.

Yes, please, keep the same license as other part of bindings.

Best regards,

+description: |
+  The PXA1908 clock subsystem generates and supplies clock to various
+  controllers within the PXA1908 SoC. The PXA1908 contains numerous clock
+  controller blocks, with the ones currently supported being APBC, APBCP, MPMU
+  and APMU roughly corresponding to internal buses.
+
+  All these clock identifiers could be found in <include/dt-bindings/marvell,pxa1908.h>.
+
+properties:
+  compatible:
+    enum:
+      - marvell,pxa1908-apbc
+      - marvell,pxa1908-apbcp
+      - marvell,pxa1908-mpmu
+      - marvell,pxa1908-apmu
+
+  reg:
+    maxItems: 1
+
+  '#clock-cells':
+    const: 1
+
+required:
