[PATCH 1/3] dt-bindings: interconnect: Add Qualcomm ipq5210 support

[Varadarajan Narayanan]

Add master/slave ids for Qualcomm ipq5210 Network-On-Chip
interfaces. This will be used by the gcc-ipq5210 driver
for providing interconnect services using the icc-clk framework.

[PATCH 2/3] clk: qcom: ipq5210: Use icc-clk for enabling NoC related clocks

[Varadarajan Narayanan]

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

[PATCH 3/3] arm64: dts: qcom: ipq5210: Enable interconnect capability to clock controller

[Varadarajan Narayanan]

Add 'interconnect-cells' to the clock controller node. This will be
used for enabling NOC related clocks using icc-clk framework.
