Do you want me to resend the series with patch 1 commit message
adjusted? There were no other changes requested as far as I can tell.

I think the current commit message there is fine, especially if you add
the Link: tag during applying. The extra context will be there.

If you want me to resend, I would just replace the second paragraph in
patch 1 with the following:

---
On MDM9607 and other recent SoCs, the QPIC hardware requires 3 clocks
(ahb, core, aon). However, the access to these clocks is restricted to
the RPM firmware that controls the shared power resources for the whole
SoC. The clocks cannot be controlled separately, there is only a single
RPM_SMD_QPIC_CLK clock that implicitly enables all of the 3 clocks.
The only exception to this are some IPQ* SoC that are not using RPM,
there the clocks are directly controlled by the kernel via the clock
controller (GCC). Require only one clock in the dt-bindings for MDM9607
to avoid having to define dummy clock entries.

Thanks,
Stephan
