Issues where identified with the QMP PHY binding, that would prevent

binding for the recently introduced SC8280XP, which broke USB. This
adjusts the USB PHY nodes to the new binding. The reset signal for the
first QMP PHY is corrected as well.

The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus 6P,
to avoid instabilities caused by use of protected memory regions.
The compatible for the MSM8992 TCSR mutex is corrected as well.

While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like

ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':

I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like

arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]

As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

drm/i915/dsi: add support for ICL+ native MIPI GPIO sequence

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.

MIPI sequence v4 also adds a flag to fall back to non-native sequences.

v5:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler()
  too (Ville)
- References instead of Closes issue 6131 because this does not fix everything

v4:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville)

v3:
- Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>)

v2:
- Fix HPD pin output set (impacts GPIOs 0 and 5)
- Fix GPIO data output direction set (impacts GPIOs 4 and 9)
- Reduce register accesses to single intel_de_rwm()

kbuild: rpm-pkg: add libelf-devel as alternative for BuildRequires

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.

Add it as an alternative package.

BTW, if it is impossible to solve the build requirement, the final
resort would be:

    $ make RPMOPTS=--nodeps rpm-pkg

This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.

NOTE1:
  Likewise, it is possible to bypass the build dependency check for
  debian package builds:

    $ make DPKG_FLAGS=-d deb-pkg

NOTE2:
  The 'or' operator is supported since RPM 4.13. So, old distros such
  as CentOS 7 will break. I suggest installing newer rpmbuild in such

kbuild: Fix running modpost with musl libc

commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost
rule") moved 'vmlinux.o' inside modpost-args, possibly before some of
the other options. However, getopt() in musl libc follows POSIX and
stops looking for options upon reaching the first non-option argument.
As a result, the '-T' option is misinterpreted as a positional argument,
and the build fails:

  make -f ./scripts/Makefile.modpost
     scripts/mod/modpost   -E   -o Module.symvers vmlinux.o -T modules.order
  -T: No such file or directory
  make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1
  make: *** [Makefile:1960: modpost] Error 2

The fix is to move all options before 'vmlinux.o' in modpost-args.

arch: fix broken BuildID for arm64 and riscv

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac1697b ("arm64: remove special treatment for the
link order of head.o").

The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.

Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.

While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf4421 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop

Note: While the Commands Support and Effects log page has only been
mandatory since NVMe 2.0, it is widely supported because Windows requires
it for any command passthrough from userspace.
