[PATCH 0/8] Add NSS clock controller support for IPQ5332

[PATCH 0/8] Add NSS clock controller support for IPQ5332

[Kathiravan Thirumoorthy]

Add bindings, driver and devicetree node for networking sub system clock
controller on IPQ5332. Some of the nssnoc clocks present in GCC driver is
enabled by default and its RCG is configured by bootloaders, so drop
those clocks from GCC driver.

The NSS clock controller driver depends on the below patchset which adds
support for multiple configurations for same frequency.

[PATCH 1/8] clk: qcom: ipq5332: drop the few nssnoc clocks

[Kathiravan Thirumoorthy]

gcc_snoc_nssnoc_clk, gcc_snoc_nssnoc_1_clk, gcc_nssnoc_nsscc_clk are
enabled by default and it's RCG is properly configured by bootloader.

Some of the NSS clocks needs these clocks to be enabled. To avoid
these clocks being disabled by clock framework, drop these entries.

This is not the way to prevent Linux from disabling the clocks. The way
is to mark them as critical, so I do not think you provided accurate
rationale for bindings change.

Qualcomm IPQ5332

This applies to all your patches in all your patchsets in entire
Qualcomm organisation. You add code to common, upstream Linux kernel
where hundreds of companies also contribute. Except me and few more
folks, no one knows what is IPQ5332. Other 5000 developers do not know.
Other millions of users do not know.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation


so with "clk" suffix, e.g. cmn-pll-nss-1-clk.

The maskrom or something later on?

Perhaps pm_clk could be an option for you?

Instead of this patch just drop the clks from the table and enable the
clks during probe with register writes.

Thanks for the suggestion Stephen, will handle this way in V2. Between, 
I think still the entries in the dt-bindings can be dropped along with 
the entries in the clock table?
