Subject: Re: [PATCH v6 15/15] ARM: dts: qcom: add syscon and cxo/pxo clock to
 gcc node for ipq8064

AFAICT the rest of the series has been picked up in clk-for-5.18, but I
don't see this there or in dts-for-5.18. It's required for a
functioning tsens driver on IPQ8064 so it would be nice to see it landed.
