[PATCH v6 5/6] clk: qcom: ipq9574: Use icc-clk for enabling NoC related clocks

From: Varadarajan Narayanan
Date: Tue Apr 02 2024 - 06:37:58 EST


Use the icc-clk framework to enable few clocks to be able to
create paths and use the peripherals connected on those NoCs.

v6: Move enum to dt-bindings and share between here and DT
first_id -> icc_first_node_id
v5: Split from common.c changes into separate patch
No functional changes
