Yang YingliangandGreg Kroah-Hartman 0967f1d9f1 interconnect: fix error handling in qnoc_probe() 
[ Upstream commit 273f74a2e7 ]

Add missing clk_disable_unprepare() and clk_bulk_disable_unprepare()
in the error path in qnoc_probe(). And when qcom_icc_qos_set() fails,
it needs remove nodes and disable clks.

Georgi Djakov e0d855b576 Merge branch 'icc-enable-mask' into icc-next 
As pointed out by Bjorn and Mike in [1], we can simplify the handling
of enable_mask-based BCMs. This series attempts to do so and fixes a bug
that snuck in.

Gave a quick spin on 8450, doesn't seem to have exploded.

BCMs with an enable_mask expect to only have that specific value written
to them. The current implementation only works by miracle for BCMs with
enable mask == BIT(0), as the minimal vote we've been using so far just
so happens to be equal to that.

Use the correct value with keepalive voting.

We don't need all the complex arithmetic for BCMs utilizing enable_mask,
as all we need to do is to determine whether there's any user (or
keepalive) asking for it to be on.

Separate the logic for such BCMs for a small speed boost.

Kees CookandGeorgi Djakov dd4904f3b9 interconnect: qcom: Annotate struct icc_onecell_data with __counted_by 
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct icc_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

Enable the generic .sync_state callback to ensure there are no
outstanding votes that would waste power.

Generally one would need a bunch of interface clocks to access the QoS
registers when trying to go over all possible nodes during sync_state,
but QCM2290 surprisingly does not seem to require any such handling.

Rob HerringandGeorgi Djakov cff66ace51 interconnect: Explicitly include correct DT includes 
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Konrad DybcioandBjorn Andersson 17fc623e0f interconnect: qcom: icc-rpm: Fix bandwidth calculations 
Up until now, we've been aggregating the bandwidth values and only
dividing them by the bus width of the source node. This was completely
wrong, as different nodes on a given path may (and usually do) have
varying bus widths.  That in turn, resulted in the calculated clock rates
being completely bogus - usually they ended up being much higher, as
NoC_A<->NoC_B links are very wide.

Since we're not using the aggregate bandwidth value for anything other
than clock rate calculations, remodel qcom_icc_bus_aggregate() to
calculate the per-context clock rate for a given provider, taking into
account the bus width of every individual node.

Konrad DybcioandBjorn Andersson 32846c4a8f interconnect: qcom: icc-rpm: Set bandwidth on both contexts 
Up until now, for some reason we've only been setting bandwidth values
on the active-only context. That pretty much meant that RPM could lift
all votes when entering sleep mode. Or never sleep at all.

That in turn could potentially break things like USB wakeup, as the
connection between APSS and SNoC/PNoC would simply be dead.

Set the values appropriately.

SMD RPM only provides two buckets, one each for the active-only and
active-sleep RPM contexts. Use the correct constant to allocate and
operate on them.

This will make the qcom,icc.h header no longer work with this driver,
mostly because.. it was never meant to! The commit that introduced
bucket support to SMD RPM was trying to shove a square into a round
hole and it did not work out very well. That said, there are no
active users of SMD RPM ICC + qcom,icc.h, so that doesn't hurt.
