1cef9f2d1e interconnect: qcom: Add MSM8909 interconnect provider driver 
Add driver for interconnect busses found in MSM8909 based platforms.
The topology consists of three NoCs that are partially controlled by
a RPM processor.

In the downstream/vendor kernel from Qualcomm there is an additional
"mm-snoc". However, it actually ends up using the same RPM "snoc_clk"
as the normal "snoc". It looks like this is actually the same NoC
in hardware and the "mm-snoc" was only defined to assign a different
"qcom,util-fact" to increase bandwidth requests by a static margin.
In mainline we can represent this by assigning the equivalent "ab_coeff"
to all the nodes that are part of "mm-snoc" downstream.

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.

1a14b1ac39 interconnect: qcom: Add QCM2290 driver support 
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).

f80a1d4143 interconnect: qcom: Add SDM660 interconnect provider driver 
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.
