Subject: [PATCH v6 1/6] dt-bindings: interconnect: Add Qualcomm IPQ9574 support

Add interconnect-cells to clock provider so that it can be
used as icc provider.

Add master/slave ids for Qualcomm IPQ9574 Network-On-Chip
interfaces. This will be used by the gcc-ipq9574 driver
that will for providing interconnect services using the
icc-clk framework.

Signed-off-by: Varadarajan Narayanan <quic_varada@...cinc.com>

v6:
Removed Reviewed-by: Krzysztof Kozlowski
Redefine the bindings such that driver and DT can share them

v3:
Squash Documentation/ and include/ changes into same patch

qcom,ipq9574.h
	Move 'first id' to clock driver
