2019-08-20	drivers: qcom: Add BCM vote macro to header	Jordan Crouse	1	-18/+1
	The macro to generate a Bus Controller Manager (BCM) TCS command is used by the interconnect driver but might also be interesting to other drivers that need to construct TCS commands for sub processors so move it out of the sdm845 specific file and into the header.

2019-08-15	interconnect: qcom: remove COMPILE_TEST from CONFIG_INTERCONNECT_QCOM_QCS404	Mao Wenan	1	-1/+1
	There is one compilation error when CONFIG_INTERCONNECT_QCOM_QCS404=y and CONFIG_INTERCONNECT_QCOM_SMD_RPM=y, as well as CONFIG_COMPILE_TEST=y, but CONFIG_QCOM_SMD_RPM is not set, logs as below: drivers/interconnect/qcom/smd-rpm.o: In function `qcom_icc_rpm_smd_send': smd-rpm.c:(.text+0xe4): undefined reference to `qcom_rpm_smd_write' Makefile:1071: recipe for target 'vmlinux' failed make: *** [vmlinux] Error 1 This is because INTERCONNECT_QCOM_QCS404 depends on QCOM_SMD_RPM \|\| COMPILE_TEST. Here CONFIG_COMPILE_TEST=y, so CONFIG_INTERCONNECT_QCOM_SMD_RPM is selected. If CONFIG_QCOM_SMD_RPM is not set, then qcom_rpm_smd_write() is not defined, and compilation error happen. Fix this by removing COMPILE_TEST from CONFIG_INTERCONNECT_QCOM_QCS404.

2019-08-13	interconnect: qcom: Add QCS404 interconnect provider driver	Bjorn Andersson	3	-0/+550
	Add driver for the interconnect buses found in Qualcomm QCS404-based platforms. The topology consists of three NoCs that are controlled by a remote processor. This remote processor collects the aggregated bandwidth for each master-slave pairs.

2019-08-13	interconnect: qcom: Add interconnect RPM over SMD driver	Georgi Djakov	4	-0/+97
	On some Qualcomm SoCs, there is a remote processor, which controls some of the Network-On-Chip interconnect resources. Other CPUs express their needs by communicating with this processor. Add a driver to handle communication with this remote processor. Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
2019-08-13	interconnect: qcom: Add tagging and wake/sleep support for sdm845	David Dai	1	-31/+108
	Add support for wake and sleep commands by using a tag to indicate whether or not the aggregate and set requests fall into execution state specific bucket.

2019-08-13	interconnect: Add support for path tags	Georgi Djakov	1	-1/+1
	Consumers may have use cases with different bandwidth requirements based on the system or driver state. The consumer driver can append a specific tag to the path and pass this information to the interconnect platform driver to do the aggregation based on this state. Introduce icc_set_tag() function that will allow the consumers to append an optional tag to each path. The aggregation of these tagged paths is platform specific.
