[PATCH v3 00/10] Add Network Subsystem (NSS) clock controller support for IPQ5424 SoC

[Luo Jie]

The NSS clock controller on the IPQ5424 SoC provides clocks and resets
to the networking related hardware blocks such as the Packet Processing
Engine (PPE) and UNIPHY (PCS). Its parent clocks are sourced from the
GCC, CMN PLL, and UNIPHY blocks.

Additionally, register the gpll0_out_aux GCC clock, which serves as one
of the parent clocks for some of the NSS clocks.

The NSS NoC clocks are also enabled to use the icc-clk framework, enabling
the creation of interconnect paths for the network subsystem’s connections
with these NoCs.

The NSS clock controller receives its input clocks from the CMN PLL outputs.
The related patch series which adds support for IPQ5424 SoC in the CMN PLL
driver is listed below.

Changes in v3:
- Remove frequency suffix from clock names for PPE and NSS clocks in
  IPQ9574 DT binding and DTS.
- Update IPQ5424 DT bindings and DTS to as per new PPE and NSS clock names.
- Expand the register region of IPQ5424 NSSCC to utilize the entire 0x100_000
  address range, ensuring inclusion of the wrapper region.
- Collect the reviewed-by tags.
- Link to v2: https://lore.kernel.org/r/20250627-qcom_ipq5424_nsscc-v2-0-8d392f65102a@quicinc.com

Changes in v2:
- Add new, separate clock names "nss" and "ppe" in dtbindings to support
  the IPQ5424 SoC.
- Wrap the commit message body at 75 columns.
- Fix the indentation issue in the `IPQ_NSSCC_5424` Kconfig entry.
- Enhance the commit message for the defconfig patch to clarify the requirement
  for enabling `IPQ_NSSCC_5424`.
- Link to v1: https://lore.kernel.org/r/20250617-qcom_ipq5424_nsscc-v1-0-4dc2d6b3cdfc@quicinc.com
