+description: |
+  The MStar/SigmaStar MSC313 and later ARMv7 chips have an MPLL block that
+  takes the external xtal input and multiplies it to create a high
+  frequency clock and divides that down into a number of clocks that
+  peripherals use.

+  compatible:
+    const: mstar,msc313-mpll

+  clock-output-names:

+    description: |
+      This should provide a name for the internal PLL clock and then
+      a name for each of the divided outputs.
