[PATCH 2/7] clk: qcom: gcc-ipq9574: Add PCIe pipe clocks

[Alexandru Gagniuc]

The IPQ9574 has four PCIe "pipe" clocks. These clocks are required by
PCIe PHYs. Port the pipe clocks from the downstream kernel.

I did not get half of this patchset. Are you sure you are CC-ing everyone?

The other changes are driver code that implements these DT bindings. I 
used --cc-cmd of git send-email to find the maintainers. I'll manually 
CC you to the other patches in V2.
