This patch series aims to add Operating State Manager (OSM) L3
interconnect provider support on SDM845 and SC7180 SoCs to handle
bandwidth requests from CPU to scale L3 caches.

V5:
 * addressed misc review comments from Georgi
 * allow icc node ids to be used across multiple providers
 * picked up Rob's R-b and Ack

V4:
 * add SC7180 support
 * use icc_std_aggregate
 * use icc_nodes_remove
 * fixup Evan's review comments.

v3:
 * switched the dt-bindings to dual-license
 * rebased to linux-next

v2:
 * addressed review comments from Evan
 * dropped unused gpu icc node on SDM845 SoC

Depends on:
SDM845 icc refactor: https://patchwork.kernel.org/cover/11372211/
SC7180 icc support: https://patchwork.kernel.org/cover/11404167/
