The PMI8998 PMIC has a WLED backlight controller, which is used on
most MSM8998 and SDM845 based devices: add a base configuration for
it and keep it disabled.

This contains only the PMIC specific configuration that does not
change across boards; parameters like number of strings, OVP and
current limits are product specific and shall be specified in the
product DT in order to achieve functionality.

The sc7180's dynamic-power-coefficient violates the device tree bindings.
The bindings (arm/cpus.yaml) say that the units for the
dynamic-power-coefficient are supposed to be "uW/MHz/V^2". The ones for
sc7180 aren't this. Qualcomm arbitrarily picked 100 for the "little" CPUs
and then picked a number for the big CPU based on this.

At the time, there was a giant dicussion about this. Apparently Qualcomm
Engineers were instructed not to share the actual numbers here. As part
of the discussion, I pointed out [1] that these numbers shouldn't really
be secret since once a device is shipping anyone can just run a script
and produce them. This patch is the result of running the script I posted
in that discussion on sc7180-trogdor-coachz, which is currently available
for purchase by consumers.

[1] https://lore.kernel.org/r/CAD=FV=U1FP0e3_AVHpauUUZtD-5X3XCwh5aT9fH_8S_FFML2Uw@mail.gmail.com/

I ran the script four times, measuring little, big, little, big. I used
the 64-bit version of dhrystone 2.2 in my test. I got these results:

As you can see, the calculations aren't perfectly consistent but
roughly you could say about 480 for big and 137 for little.

The ratio between these numbers isn't quite the same as the ratio
between the two numbers that Qualcomm used. Perhaps this is because
Qualcomm measured something slightly different than the 64-bit version
of dhrystone 2.2 or perhaps it's because they fudged these numbers a
bit (and fudged the capacity-dmips-mhz). As per discussion [2], let's
use the numbers I came up with and also un-fudge
capacity-dmips-mhz. While unfudging capacity-dmips-mhz, let's scale it
so that bigs are 1024 which seems to be the common practice.

In general these numbers don't need to be perfectly exact. In fact,
they can't be since the CPU power depends a lot on what's being run on
the CPU and the big/little CPUs are each more or less efficient in
different operations. Historically running the 32-bit vs. 64-bit
versions of dhrystone produced notably different numbers, though I
didn't test this time.

We also need to scale all of the sustainable-power numbers by the same
amount. I scale ones related to the big CPUs by the adjustment I made
to the big dynamic-power-coefficient and the ones related to the
little CPUs by the adjustment I made to the little
dynamic-power-coefficient.

The QFPROM iospace was (erroneously, I believe) set to the uncalibrated
fuse start address, but every driver only needs - and will always only
need - only calibrated values.

Move the iospace forward to the calibrated values start to avoid
offsetting every fuse definition.
Obviously, the only defined fuse (qusb2_hstx_trim) was also fixed to
remove the offset, in order to comply with this change.

The entry/exit latency and minimum residency in state for the idle
states of MSM8998 were ..bad: first of all, for all of them the
timings were written for CPU sleep but the min-residency-us param
was miscalculated (supposedly, while porting this from downstream);
Then, the power collapse states are setting PC on both the CPU
cluster *and* the L2 cache, which have different timings: in the
specific case of L2 the times are higher so these ones should be
taken into account instead of the CPU ones.

This parameter misconfiguration was not giving particular issues
because on MSM8998 there was no CPU scaling at all, so cluster/L2
power collapse was rarely (if ever) hit.
When CPU scaling is enabled, though, the wrong timings will produce
SoC unstability shown to the user as random, apparently error-less,
sudden reboots and/or lockups.

This set of parameters are stabilizing the SoC when CPU scaling is
ON and when power collapse is frequently hit.

Pull more RISC-V updates from Palmer Dabbelt:

 - A pair of defconfig additions, for NVMe and the EFI filesystem
   localization options.

 - A larger address space for stack randomization.

 - A cleanup to our install rules.

 - A DTS update for the Microchip Icicle board, to fix the serial
   console.

Pull coccinelle updates from Julia Lawall:
 "These changes update some existing semantic patches with
  respect to some recent changes in the kernel.

  Specifically, the change to kvmalloc.cocci searches for
  kfree_sensitive rather than kzfree, and the change to
  use_after_iter.cocci adds list_entry_is_head as a valid
  use of a list iterator index variable after the end of
  the loop"

That doesn't result in any changes to tooling as no new ioctl were
added (at least not perceived by tools/perf/trace/beauty/drm_ioctl.sh).

To pick the change in:

It adds a new ioctl, but we are still not using that to generate tables
for 'perf trace', so no changes in tooling.

Some distributions, like debian, don't link perf with libbfd. Add a
build flag to make this configuration buildable and testable.

Currently perf saves a build-id with size but old versions assumes the
size of 20.  In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.

I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data.  The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

  symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

  $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf

      Build ID: 53e4c2f42a4c61a2d632d92a72afa08f

Let's fix this by allowing trailing zeros if the size is different.
