2022-07-15Merge branch 'icc-rpm' into icc-nextGeorgi Djakov1-0/+3
This patch set is to support bucket in icc-rpm driver, so it implements the similar mechanism in the icc-rpmh driver. It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Link: https://lore.kernel.org/r/20220712015929.2789881-1-leo.yan@linaro.org Signed-off-by: Georgi Djakov <djakov@kernel.org>
2022-07-12interconnect: qcom: Move qcom_icc_xlate_extended() to a common fileLeo Yan1-0/+3
since there have conflict between two headers icc-rpmh.h and icc-rpm.h, the function qcom_icc_xlate_extended() is declared in icc-rpmh.h thus it cannot be used by icc-rpm driver. Move the function to a new common file icc-common.c so that allow it to be called by multiple drivers.

It adds interconnect driver support for QCM2290 platform. The topology consists of 3 NoCs: BIMC, Config NoC (CNOC) and System NoC (SNOC). SNOC is a QCOM_ICC_QNOC type device, as well as its 3 virtual child devices, QUP, MMNRT and MMRT. QUP is owned by RPM and thus has no .regmap_cfg, while the other 2 share the same .regmap_cfg with SNOC (parent).

Introduce a driver for the Qualcomm interconnect busses found in the SDM630/SDM636/SDM660 SoCs. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs. On a note, these chips are managing the "bus QoS" in a "hybrid" fashion: some of the paths in the topology are managed through (and by, of course) the RPM uC, while some others are "AP Owned", meaning that the AP shall do direct writes to the appropriate QoS registers for the specific paths and ports, instead of sending an indication to the RPM and leaving the job to that one.
