[PATCH v5 2/9] dt-bindings: clock: cs2000-cp: document aux-output-source
From: Daniel Mack <daniel@zonque.org>

Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:

This new optional property can be used to control the function of the auxiliary output pin. Introduce a new dt-bindings include file that contains the numerical values.
