Pull driver core updates from Greg KH:
 "Here is the large set of driver core changes for 6.4-rc1.

  Once again, a busy development cycle, with lots of changes happening
  in the driver core in the quest to be able to move "struct bus" and
  "struct class" into read-only memory, a task now complete with these
  changes.

  This will make the future rust interactions with the driver core more
  "provably correct" as well as providing more obvious lifetime rules
  for all busses and classes in the kernel.

  The changes required for this did touch many individual classes and
  busses as many callbacks were changed to take const * parameters
  instead. All of these changes have been submitted to the various
  subsystem maintainers, giving them plenty of time to review, and most
  of them actually did so.

  Other than those changes, included in here are a small set of other
  things:

   - kobject logging improvements

   - cacheinfo improvements and updates

   - obligatory fw_devlink updates and fixes

   - documentation updates

   - device property cleanups and const * changes

   - firwmare loader dependency fixes.

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

Pull more devicetree updates from Rob Herring:

 - First part of DT header detangling dropping cpu.h from of_device.h
   and replacing some includes with forward declarations. A handful of
   drivers needed some adjustment to their includes as a result.

 - Refactor of_device.h to be used by bus drivers rather than various
   device drivers. This moves non-bus related functions out of
   of_device.h. The end goal is for of_platform.h and of_device.h to
   stop including each other.

 - Refactor open coded parsing of "ranges" in some bus drivers to use DT
   address parsing functions

 - Add some new address parsing functions of_property_read_reg(),
   of_range_count(), and of_range_to_resource() in preparation to
   convert more open coded parsing of DT addresses to use them.

 - Treewide clean-ups to use of_property_read_bool() and
   of_property_present() as appropriate. The ones here are the ones that
   didn't get picked up elsewhere.

Pull cpufreq/ARM updates for 6.4 from Viresh Kumar:

"- Add opp and bandwidth support to tegra194 cpufreq driver (Sumit
   Gupta).

 - Use of_property_present() for testing DT property presence (Rob
   Herring).

 - Remove MODULE_LICENSE in non-modules (Nick Alcock).

 - Add SM7225 to cpufreq-dt-platdev blocklist (Luca Weiss).

 - Optimizations and fixes for qcom-cpufreq-hw driver (Krzysztof
   Kozlowski, Konrad Dybcio, and Bjorn Andersson).

 - DT binding updates for qcom-cpufreq-hw driver (Konrad Dybcio and
   Bartosz Golaszewski).

 - Updates and fixes for mediatek driver (Jia-Wei Chang and
   AngeloGioacchino Del Regno)."

cpufreq_verify_current_freq checks() if the frequency returned by
the hardware has a slight delta with the valid frequency value
last set and returns "policy-&gt;cur" if the delta is within "1 MHz".
In the comparison, "policy-&gt;cur" is in "kHz" but it's compared
against HZ_PER_MHZ. So, the comparison range becomes "1 GHz".

Fix this by comparing against KHZ_PER_MHZ instead of HZ_PER_MHZ.

<title>cpufreq: tegra194: add OPP support and set bandwidth</title>

Add support to use OPP table from DT in Tegra194 cpufreq driver.
Tegra SoC's receive the frequency lookup table (LUT) from BPMP-FW.
Cross check the OPP's present in DT against the LUT from BPMP-FW
and enable only those DT OPP's which are present in LUT also.

The OPP table in DT has CPU Frequency to bandwidth mapping where
the bandwidth value is per MC channel. DRAM bandwidth depends on the
number of MC channels which can vary as per the boot configuration.
This per channel bandwidth from OPP table will be later converted by
MC driver to final bandwidth value by multiplying with number of
channels before sending the request to BPMP-FW.

If OPP table is not present in DT, then use the LUT from BPMP-FW
directy as the CPU frequency table and not do the DRAM frequency
scaling which is same as the current behavior.

Now, as the CPU Frequency table is being controlling through OPP
table in DT. Keeping fewer entries in the table will create less
frequency steps and can help to scale fast to high frequencies
when required.

Removing the include of cpu.h from of_device.h causes an error:

drivers/cpufreq/sun50i-cpufreq-nvmem.c:42:19: error: implicit declaration of function ‘get_cpu_device’; did you mean ‘get_device’? [-Werror=implicit-function-declaration]

As of_device.h is not otherwise needed, it can be replaced with of.h
(also implicitly included).

Now that of_cpu_device_node_get() is defined in of.h, of_device.h is just
implicitly including other includes, and is no longer needed. Adjust the
include files with what was implicitly included by of_device.h (cpu.h and
of.h) and drop including of_device.h.
