ASoC: Updates for v7.0

This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:

- Generic SDCA support for reporting jack events.
- Continuing platform support, cleanup and feature improements for the
AMD, Intel, Qualcomm and SOF code.
- Platform description improvements for the Cirrus drivers.
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B.

We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.

manufacturer did not provide a firmware file, only a sequence of
register writes to each device to enable and disable them.

Add support for this *specific* configuration in the AW87390 driver.
Since we are relying on a device specific sequence I am using a
device specific compatible string. This driver does not currently
support the aw87391 for any other device as I have none to test
with valid firmware. Attempts to create firmware with the AwinicSCPv4

Merge branch 'resolve_btfids-support-for-btf-modifications'

Ihor Solodrai says:

====================
resolve_btfids: Support for BTF modifications

This series changes resolve_btfids and kernel build scripts to enable
BTF transformations in resolve_btfids. Main motivation for enhancing
resolve_btfids is to reduce dependency of the kernel build on pahole
capabilities [1] and enable BTF features and optimizations [2][3]
particular to the kernel.

Patches #1-#4 in the series are non-functional changes in
resolve_btfids.

Patch #5 makes kernel build notice pahole version changes between
builds.

Patch #6 changes minimum version of pahole required for
CONFIG_DEBUG_INFO_BTF to v1.22

Patch #7 makes a small prep change in selftests/bpf build.

The last patch (#8) makes significant changes in resolve_btfids and
introduces scripts/gen-btf.sh. See implementation details in the patch
description.

resolve_btfids: Change in-place update with raw binary output

Currently resolve_btfids updates .BTF_ids section of an ELF file
in-place, based on the contents of provided BTF, usually within the
same input file, and optionally a BTF base.

Change resolve_btfids behavior to enable BTF transformations as part
of its main operation. To achieve this, in-place ELF write in
resolve_btfids is replaced with generation of the following binaries:
* ${1}.BTF with .BTF section data
* ${1}.BTF_ids with .BTF_ids section data if it existed in ${1}
* ${1}.BTF.base with .BTF.base section data for out-of-tree modules

The execution of resolve_btfids and consumption of its output is
orchestrated by scripts/gen-btf.sh introduced in this patch.

The motivation for emitting binary data is that it allows simplifying
resolve_btfids implementation by delegating ELF update to the $OBJCOPY
tool [1], which is already widely used across the codebase.

There are two distinct paths for BTF generation and resolve_btfids
application in the kernel build: for vmlinux and for kernel modules.

For the vmlinux binary a .BTF section is added in a roundabout way to
ensure correct linking. The patch doesn't change this approach, only
the implementation is a little different.

Before this patch it worked as follows:

* pahole consumed .tmp_vmlinux1 [2] and added .BTF section with
llvm-objcopy [3] to it
* then everything except the .BTF section was stripped from .tmp_vmlinux1
into a .tmp_vmlinux1.bpf.o object [2], later linked into vmlinux
* resolve_btfids was executed later on vmlinux.unstripped [4],
updating it in-place

After this patch gen-btf.sh implements the following:

* pahole consumes .tmp_vmlinux1 and produces a *detached* file with
raw BTF data
* resolve_btfids consumes .tmp_vmlinux1 and detached BTF to produce
(potentially modified) .BTF, and .BTF_ids sections data
* a .tmp_vmlinux1.bpf.o object is then produced with objcopy copying
BTF output of resolve_btfids
* .BTF_ids data gets embedded into vmlinux.unstripped in
link-vmlinux.sh by objcopy --update-section

For kernel modules, creating a special .bpf.o file is not necessary,
and so embedding of sections data produced by resolve_btfids is
straightforward with objcopy.

With this patch an ELF file becomes effectively read-only within
resolve_btfids, which allows deleting elf_update() call and satellite
code (like compressed_section_fix [5]).

Endianness handling of .BTF_ids data is also changed. Previously the
"flags" part of the section was bswapped in sets_patch() [6], and then
Elf_Type was modified before elf_update() to signal to libelf that
bswap may be necessary. With this patch we explicitly bswap entire
data buffer on load and on dump.

kbuild: Fix permissions of modules.builtin.modinfo

Currently, modules.builtin.modinfo is created with executable permissions
(0755). This is because after commit 39cfd5b12160 ("kbuild: extract
modules.builtin.modinfo from vmlinux.unstripped"), modules.builtin.modinfo
is extracted from vmlinux.unstripped using objcopy. When extracting
sections, objcopy inherits attributes from the source ELF file.

Since modules.builtin.modinfo is a data file and not an executable,
it should have regular file permissions (0644). The executable bit
can trigger warnings in Debian's Lintian tool.

Explicitly remove the executable bit after generation.
