[PATCH v2] clk: qcom: ipq8074: populate fw_name for all parents

[PATCH v2] clk: qcom: ipq8074: populate fw_name for all parents

[Robert Marko]

It appears that having only .name populated in parent_data for clocks
which are only globally searchable currently will not work as the clk core
won't copy that name if there is no .fw_name present as well.

So, populate .fw_name for all parent clocks in parent_data.

Is there a DT binding update for these firmware names?

Hi Stephen,
I have that name documented as part of series for passing the QMP
PCI output clock directly to GCC instead of global matching that
I wanted to send after this and PCI fixups were merged.

I can change it to match the global name, but that is a bit confusing
as pcie20_phy0_pipe_clk is actually from the Gen3 PHY but the GCC
driver was made for v1 of the SoC which was pre-production and then
it got updated to support v2 which is only supported so the name stuck
as it would break backwards compatibility.

Regards,
Robert
