Subject: [PATCH 5/6] dt-bindings: clock: qcom,msm8996-apcc: Fix clocks

From: Yassine Oudjana <[email protected]>

The clocks currently listed in clocks and clock-names are the ones
supplied by this clock controller, not the ones it consumes. Replace
them with the only clock it consumes - the on-board oscillator (XO),
and make the properties required.

I think we can not list them as required, as then older DT files won't
pass schema validation. But I'll leave this into the hands of Rob and
Krzyshtof.

Looks fine to me then. (Though Rob and Krzysztof have the deciding voice here).

The old DT files that didn't have XO defined had a wrong
compatible string to begin with (fixed in [1]), so I don't
think it's a problem.
