[PATCH v5 0/8] Add NSS clock controller support for Qualcomm IPQ5332

[PATCH v5 0/8] Add NSS clock controller support for Qualcomm IPQ5332

[Varadarajan Narayanan]

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 enable
those clocks in driver probe.

Changes in v5:
- Rebased on next-20240821
- Addressed review comments
- Dropped 'const qualifier' patches
- Dropped 'clk: qcom: ipq5332: enable few nssnoc clocks in driver probe'
- Enabled icc-clk for NSSCC
- Update ICC master/slave list
- In dt-bindings of nsscc
	Mark #power-domain-cells as false (as it is not applicable)
	Add #interconnect-cells
- Link to v4: https://lore.kernel.org/lkml/20240122-ipq5332-nsscc-v4-0-19fa30019770@quicinc.com/

Changes in v4:
- Rebased on next-20240122
- Fixed the missing space on the nsscc node
- Link to v3: https://lore.kernel.org/linux-arm-msm/20231211-ipq5332-nsscc-v3-0-ad13bef9b137@quicinc.com/

Changes in v3:
- Collected the tags
- Dropped the dt-binding patch 3/9
- Cleaned up the header file inclusion and updated the module
  description in the driver
- Used the decimal number instead of hex in the NSSCC node
- Link to v2: https://lore.kernel.org/r/20231121-ipq5332-nsscc-v2-0-a7ff61beab72@quicinc.com

[PATCH v5 8/8] arm64: defconfig: build NSS Clock Controller driver for Qualcomm IPQ5332

[Varadarajan Narayanan]

From: Kathiravan Thirumoorthy <quic_kathirav@quicinc.com>

NSSCC driver is needed to enable the ethernet interfaces and not
necessary for the bootup of the SoC, hence build it as a module.

Who generates these clocks? 300 MHz crystal?

Then this might not be GCC-like clock controller or gcc.yaml 
should not include power-domain-cells.

qcom,gcc.yaml already doesn't mark #power-domain-cells as required, so
it should be fine. See qcom,gcc-apq8064.yaml or qcom,gcc-ipq4019.yaml.

I know, I am not saying whether code is correct or not, but whether it
makes sense. If it does not have power domains, but instead interconnect
cells, maybe it should not be considered a "GCC" like block.

These two clocks are from the output clocks of CMN PLL.
IPQ5332 CMN PLL patches similar to [1] are in the pipeline
and should get posted soon.
