-Binding for a type of STMicroelectronics clock crossbar (VCC).
-
-The crossbar can take up to 4 input clocks and control up to 16
-output clocks. Not all inputs or outputs have to be in use in a
-particular instantiation. Each output can be individually enabled,
-select any of the input clocks and apply a divide (by 1,2,4 or 8) to
-that selected clock.
-
-This binding uses the common clock binding[1].

-
-- reg : A Base address and length of the register set.

-- clocks : from common clock binding
-
-- clock-output-names : From common clock binding. The block has 16
- clock outputs but not all of them in a specific instance
- have to be used in the SoC. If a clock name is left as
- an empty string then no clock will be created for the
- output associated with that string index. If fewer than
- 16 strings are provided then no clocks will be created
- for the remaining outputs.
