[PATCH v2 0/3] Add Qualcomm CAMNOC ICC provider

[Atanas Filipov]

This series adds a device tree binding and driver for the Qualcomm
Camera Network-on-Chip (CAMNOC) interconnect provider for SM8250.

CAMNOC is the internal AXI interconnect within the camera subsystem.
Multiple camera sub-devices (IFE, JPEG, BPS, IPE, etc.) share
CAM_CC_CAMNOC_AXI_CLK. Direct clk_set_rate() calls from each consumer
cause a last-writer-wins race. This series introduces a lightweight ICC
provider that aggregates bandwidth votes from all consumers and applies
a single clk_set_rate() call.

Changes since v1:
- dt-bindings: add all SM8250 CAMNOC master port IDs to qcom,camnoc.h
  (IFE 0/1, IFE Lite 0-4, BPS, IPE 0/1, JPEG, JPEG DMA, CDM, FD, SBI,
  ICP) with a short comment per group (Dmitry Baryshkov)
- dt-bindings: add IFE simple consumer example alongside the JPEG
  OPP-based example; clarify opp-hz and opp-peak-kBps semantics in
  comments; fix maintainer email; align provider node name with DTS
- driver: register all SM8250 CAMNOC master nodes
