I do prefer to merge only regression and important fixes after the
merge window, so I want to be able to provide justification.

IIUC we're talking about:

  arm64: dts: qcom: sc8280xp: add missing PCIe minimum OPP
  dt-bindings: PCI: qcom: Allow 'required-opps'

These don't look like a regression fix (correct me if I'm wrong), and
I can't tell whether they fix a user-visible problem, since
sc8280xp.dtsi does already contain 'required-opps' for ufs_mem_hc,
usb_0, and usb_1, which are mentioned in the commit log as covering up
the issue.

If these patches wait until v6.9, what badness ensues?
