Bandwidth monitoring (BWMON) sits between various subsytems like CPU,
GPU, Last Level caches and memory subsystem.  The BWMON can be
configured to monitor the data throuhput between memory and other
subsytems.  The throughput is measured within specified sampling window
and is used to vote for corresponding interconnect bandwidth.

Current implementation brings support for BWMON v4, used for example on
SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level
Cache (memnoc).  Usage of this BWMON allows to remove fixed bandwidth
votes from cpufreq (CPU nodes) thus achieve high memory throughput even
with lower CPU frequencies.

The driver was tested on SDM845.

Add bindings for the Qualcomm Bandwidth Monitor device providing
performance data on interconnects.  The bindings describe only BWMON CPU
(version 4), e.g. the instance which appeared for the first on Qualcomm
MSM8998 SoC and is also used on SDM845.  This BWMON device sits between
CPU and Last Level Cache Controller.

When breaking early from a for_each_available_child_of_node() loop,

Commit ac0126a0 ("soc: qcom: cmd-db: replace strncpy() with
strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine
device. From printouts I see that at bootup the function is called
with an id of "lnbclka2" which is 8 bytes big.

Previously all 8 bytes of this string were copied to the
destination. Now only 7 bytes will be copied since strscpy_pad() saves
a byte for '\0' termination.

We don't need the '\0' termination in the destination. Let's go back
to strncpy(). According to the warning:
  If a caller is using non-NUL-terminated strings, strncpy() can still
  be used, but destinations should be marked with the __nonstring
  attribute to avoid future compiler warnings.
...so we'll do that.

While we're at it, let's change the query array to use
"sizeof(ent->id)" so it can't possibly go out of sync with our later
copy.

Some sc7180 Chromebooks actually have sc7180P (known by many names,
apparently, including possibly sc7180 Pro and sc7185). This is a
sc7180 part that has slightly higher clock speeds.

The official ID number allocated to these devices by Qualcomm is 495
so we'll add an entry to the table for them. Note that currently
shipping BIOS for these devices will actually end up reporting an ID
of 407 due to a bug but eventually a new BIOS will be released which
corrects it to 495.

  delayacct: track delays from write-protect copy

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.

It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32.  It shoudln't have been a bitmap in the first
place.  The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.

The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.

So just use a regular integer.

In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).

That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953f ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
