interconnect: qcom: Add SDX55 interconnect provider driver

2021-01-27T11:11:33+00:00

Add driver for the Qualcomm interconnect buses found in SDX55 based
platforms. The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.

Based on SM8250 driver and generated from downstream dts.

interconnect: qcom: fix rpmh link failures

2020-12-28T12:03:02+00:00

When CONFIG_COMPILE_TEST is set, it is possible to build some
of the interconnect drivers into the kernel while their dependencies
are loadable modules, which is bad:

arm-linux-gnueabi-ld: drivers/interconnect/qcom/bcm-voter.o: in function `qcom_icc_bcm_voter_commit':
(.text+0x1f8): undefined reference to `rpmh_invalidate'
arm-linux-gnueabi-ld: (.text+0x20c): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2b0): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2e8): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: drivers/interconnect/qcom/icc-rpmh.o: in function `qcom_icc_bcm_init':
(.text+0x2ac): undefined reference to `cmd_db_read_addr'
arm-linux-gnueabi-ld: (.text+0x2c8): undefined reference to `cmd_db_read_aux_data'

The exact dependencies are a bit complicated, so split them out into a
hidden Kconfig symbol that all drivers can in turn depend on to get it
right.

interconnect: qcom: Add OSM L3 interconnect provider support

2020-03-03T17:02:52+00:00

On some Qualcomm SoCs, Operating State Manager (OSM) controls the
resources of scaling L3 caches. Add a driver to handle bandwidth
requests to OSM L3 from CPU on SDM845 SoCs.

interconnect: qcom: Consolidate interconnect RPMh support

2020-02-28T10:11:40+00:00

Add bcm voter driver and add support for RPMh specific interconnect
providers which implements the set and aggregate functionalities that
translates bandwidth requests into RPMh messages. These modules provide
a common set of functionalities for all Qualcomm RPMh based interconnect
providers and should help reduce code duplication when adding new
providers.
