Merge tag 'icc-6.19-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/djakov/icc into char-misc-next
Georgi writes: interconnect changes for 6.19 This pull request contains the interconnect changes for the 6.19-rc1 merge window. The core and driver changes are listed below. Core changes: - kbps_to_icc() macro optimization Driver changes: - Switch all Qualcomm RPMh interconnect drivers to use the dynamic node IDs and drop support for non-dynamic ID allocation - Add new driver and BWMON support for the Kaanapali SoC - Add QoS support for the SM6350 SoC - Add QoS support for the SA8775p SoC - Fix missing link from SNOC_PNOC to the USB 2 on MSM8996 SoC that includes also a dts change that has been acked by the maintainer - Drop the QPIC interconnect and BCM nodes for the SDX75 SoC, as these should be handled by the rpmh-clk driver - Other misc fixes Signed-off-by: Georgi Djakov <djakov@kernel.org> * tag 'icc-6.19-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/djakov/icc: (40 commits) interconnect: qcom: sm6350: enable QoS configuration interconnect: qcom: sm6350: Remove empty BCM arrays interconnect: qcom: icc-rpmh: Get parent's regmap for nested NoCs dt-bindings: interconnect: qcom,sm6350-rpmh: Add clocks for QoS dt-bindings: interconnect: qcom-bwmon: Document Kaanapali BWMONs interconnect: qcom: icc-rpmh: drop support for non-dynamic IDS interconnect: qcom: sm8750: convert to dynamic IDs interconnect: qcom: sm8650: convert to dynamic IDs interconnect: qcom: sm8550: convert to dynamic IDs interconnect: qcom: sm8450: convert to dynamic IDs interconnect: qcom: sm8350: convert to dynamic IDs interconnect: qcom: sm8150: convert to dynamic IDs interconnect: qcom: sm7150: convert to dynamic IDs interconnect: qcom: sm6350: convert to dynamic IDs interconnect: qcom: sdx75: convert to dynamic IDs interconnect: qcom: sdx65: convert to dynamic IDs interconnect: qcom: sdx55: convert to dynamic IDs interconnect: qcom: sdm670: convert to dynamic IDs interconnect: qcom: sc7180: convert to dynamic IDs interconnect: qcom: sar2130p: convert to dynamic IDs ...

+description: |
+ RPMh interconnect providers support system bandwidth requirements through
+ RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+ able to communicate with the BCM through the Resource State Coordinator (RSC)
+ associated with each execution environment. Provider nodes must point to at
+ least one RPMh device child node pertaining to their RSC and each provider
+ can map to multiple RPMh resources.
