Subject: [PATCH v5 0/7] Add OSM L3 Interconnect Provider

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/
