Commit Message

Luo Jie June 17, 2025, 12:06 p.m. UTC 
NSS clock controller provides the clocks and resets to the
networking blocks such as PPE (Packet Process Engine) and
UNIPHY (PCS) on IPQ5424 devices.

Add the compatible "qcom,ipq5424-nsscc" support based on the
current IPQ9574 NSS clock controller DT binding file.
ICC clocks are always provided by the NSS clock controller
of IPQ9574 and IPQ5424, so add interconnect-cells as required
DT property.

Also add master/slave ids for IPQ5424 networking interfaces,
which is used by nss-ipq5424 driver for providing interconnect
services using icc-clk framework.
