Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk subsystem updates from Stephen Boyd:
"This pull request is full of clk driver changes. In fact, there aren't
any changes to the clk framework this time around. That's probably
because everyone was on vacation (yours truly included). We did lose a
couple clk drivers this time around because nobody was using those
devices. That skews the diffstat a bit, but either way, nothing looks
out of the ordinary here. The usual suspects are chugging along adding
support for more SoCs and fixing bugs.

If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a
handful of patches that move the NR_CLKS define from the DT binding
header to the driver. There's even patches that migrate drivers to use
clk_parent_data and clk_hw to describe clk tree topology. It seems
that the spring (summer?) cleaning bug got some folks, or the
semiconductor shortage finally hit the software side.

New Drivers:
- StarFive JH7110 SoC clock drivers
- Qualcomm IPQ5018 Global Clock Controller driver
- Versa3 clk generator to support 48KHz playback/record with audio
codec on RZ/G2L SMARC EVK

- Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and

- Convert sun9i-mmc clock to use
devm_platform_get_and_ioremap_resource()
- Fix function name in a comment in ccu_mmc_timing.c
- Parameter name correction for ccu_nkm_round_rate()
- Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
consider alternative parent rates when determining clock rates
- Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi

interconnect changes for 6.6

This pull request contains the interconnect changes for the 6.6-rc1 merge
window which is a mix of core and driver changes with the following highlights:

Core changes:
- New generic test client driver that allows issuing bandwidth requests
between endpoints via debugfs.
- Annotate all structs with flexible array members with the __counted_by
attribute.
- Introduce new icc_bw_lock for cases where we need to serialize bandwidth
aggregation and update to decouple that from paths that require memory
allocation.

Driver changes:
- Move the Qualcomm SMD RPM bus-clocks from CCF to interconnect framework
where they actually belong. This brings power management improvements
and reduces the overhead and layering. These changes are in immutable
branch that is being pulled also into the qcom tree.
- Fixes for QUP nodes on SM8250.
- Enable sync_state and keepalive for QCM2290.
- Enable sync_state for SM8450.
- Improve enable_mask-based BCMs handling and fix some bugs.
- Add compatible string for the OSM-L3 on SDM670.
- Add compatible strings for SC7180, SM8250 and SM6350 bandwidth monitors.
- Expand and retire the DEFINE_QNODE and DEFINE_QBCM macros, which have
become ugly beasts with many different arguments.

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.

Merge branch '20230526-topic-smd_icc-v7-0-09c78c175546@linaro.org' into clk-for-6.6

This series reshuffles things around, moving the management of SMD RPM
bus clocks to the interconnect framework where they belong. This helps
us solve a couple of issues:

1. We can work towards unused clk cleanup of RPMCC without worrying
about it killing some NoC bus, resulting in the SoC dying.
Deasserting actually unused RPM clocks (among other things) will
let us achieve "true SoC-wide power collapse states", also known as
VDD_LOW and VDD_MIN.

2. We no longer have to keep tons of quirky bus clock ifs in the icc
driver. You either have a RPM clock and call "rpm set rate" or you
have a single non-RPM clock (like AHB_CLK_SRC) or you don't have any.

3. There's less overhead - instead of going through layers and layers of
the CCF, ratesetting comes down to calling max() and sending a single
RPM message. ICC is very very dynamic so that's a big plus.

The clocks still need to be vaguely described in the clk-smd-rpm driver,
as it gives them an initial kickoff, before actually telling RPM to
enable DVFS scaling. After RPM receives that command, all clocks that
have not been assigned a rate are considered unused and are shut down
in hardware, leading to the same issue as described in point 1.

We can consider marking them __initconst in the future, but this series
is very fat even without that..

Apart from that, it squashes a couple of bugs that really need fixing..

The series is merged through a topic branch to manage the dependencies
between interconnect, Qualcomm clocks and Qualcomm SoC.

interconnect: qcom: icc-rpm: Control bus rpmcc from icc

The sole purpose of bus clocks that were previously registered with
rpmcc was to convey the aggregated bandwidth to RPM. There's no good
reason to keep them outside the interconnect framework, as it only
adds to the plentiful complexity.

Add the required code to handle these clocks from within SMD RPM ICC.

RPM-owned bus clocks are no longer considered a thing, but sadly we
have to allow for the existence of HLOS-owned bus clocks, as some
(mostly older) SoCs (ab)use these for bus scaling (e.g. MSM8998 and
&mmcc AHB_CLK_SRC).

This in turn is trivially solved with a single *clk, which is filled
and used iff qp.bus_clk_desc is absent and we have a "bus" clock-names
entry in the DT node.

This change should(tm) be fully compatible with all sorts of old
Device Trees as far as the interconnect functionality goes (modulo
abusing bus clock handles or wrongly using the qcom,icc.h binding,
but that's a mistake in and of itself).

- IIO driver updates and additions

- W1 driver updates and fixes (and a new maintainer!)

- FPGA driver updates and fixes

- Counter driver updates

- Extcon driver updates

- Interconnect driver updates

- Coresight driver updates

- mfd tree tag merge needed for other updates on top of that, lots of
small driver updates as patches, including:

- static const updates for class structures

- nvmem driver updates

- pcmcia driver fix

- lots of other small driver updates and fixes

All of these have been in linux-next for a while with no reported
problems"

interconnect changes for 6.5

This pull request contains the interconnect changes for the 6.5-rc1 merge
window which is a mix of core and driver changes with the following highlights:

- Support for configuring QoS on the Qualcomm's RPM-based platforms, that
required special handling of some interface (non-scaling) clocks.
- Support for clock-based interconnect providers for cases when clock
corresponds to bus bandwidth. This is used to enable CPU cluster bandwidth
scaling on MSM8996 platforms. One patch is touching a file in the clock
subsystem that has been acked by the maintainer.

Core changes:
interconnect: add clk-based icc provider support
interconnect: icc-clk: fix modular build
interconnect: drop unused icc_get() interface

Driver changes:
interconnect: qcom: rpm: Rename icc desc clocks to bus_blocks
interconnect: qcom: rpm: Rename icc provider num_clocks to num_bus_clocks
interconnect: qcom: rpm: Drop unused parameters
interconnect: qcom: rpm: Set QoS registers only once
interconnect: qcom: rpm: Handle interface clocks
interconnect: qcom: icc-rpm: Enforce 2 or 0 bus clocks
interconnect: qcom: rpm: Don't use clk_get_optional for bus clocks anymore
interconnect: qcom: msm8996: Promote to core_initcall

interconnect: qcom: icc-rpm: Enforce 2 or 0 bus clocks

For SMD RPM bus scaling to work, we need a pair of sleep-wake clocks.
The variable number of them we previously supported was only a hack
to keep the clocks required for QoS register access, but now that
these are separated, we can leave bus_clks to the actual bus clocks.

In cases where there is no actual bus scaling (such as A0NoC on MSM8996
and GNoC on SDM660 where the HLOS is only supposed to program the QoS
registers and the bus is either static or controlled remotely), allow
for no clock scaling with a boolean property.

Remove all the code related to allowing an arbitrary number of bus_clks,
replace the number by BUS_CLK_MAX (= 2) and guard the bus clock paths
to ensure they are not taken on non-scaling buses.

interconnect: qcom: rpm: Handle interface clocks

Some (but not all) providers (or their specific nodes) require
specific clocks to be turned on before they can be accessed. Failure
to ensure that results in a seemingly random system crash (which
would usually happen at boot with the interconnect driver built-in),
resulting in the platform not booting up properly.

Limit the number of bus_clocks to 2 (which is the maximum that SMD
RPM interconnect supports anyway) and handle non-scaling clocks
separately. Update MSM8996 and SDM660 drivers to make sure they do
not regress with this change.

This unfortunately has to be done in one patch to prevent either
compile errors or broken bisect.
