[PATCH v3 1/3] dt-bindings: clock: qcom,camcc-sm8250: add interconnect provider
From: Atanas Filipov
Date: Fri Oct 16 2026 - 13:09:15 EST
CAM_CC_CAMNOC_AXI_CLK is shared by several camera blocks. Setting its
rate directly from each consumer means the last writer wins.
Add #interconnect-cells so the camera clock controller can act as an
icc-clk provider, and add the camera NoC AXI master/slave IDs.
Consumers request bandwidth on this path and the interconnect core
aggregates the requests.
