[PATCH 2/5] dt-bindings: arm: coresight: Allow atclk for static funnel

[Leo Yan]

Static funnels have no programmable registers and need no APB
programming clock. They can still require a trace clock for the ATB
datapath.

Document an optional atclk input. The CoreSight funnel driver already
enables it when present.
