Subject[PATCH v6 2/5] dt-bindings: clock: Add S700 support for Actions Semi Soc's
Date
Add clock bindings constants for action S700
Maintain common clock dt-bindings for Actions Semi SoC's
S700 and S900.

External clocks:

The hosc clock used as input for the plls is generated outside the SoC. It is
expected that it is defined using standard clock bindings as "hosc".
