ASoC: Updates for v5.16
This is an unusually large set of updates, mostly a large crop of unusually big drivers coupled with extensive overhauls of existing code. There's a SH change here for the DAI format terminology, the change is straightforward and the SH maintainers don't seem very active.
- A new version of the audio graph card which supports a wider range of systems. - Move of the Cirrus DSP framework into drivers/firmware to allow for future use by non-audio DSPs. - Several conversions to YAML DT bindings. - Continuing cleanups to the SOF and Intel code. - A very big overhaul of the cs42l42 driver, correcting many problems. - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS, RT5682S, and RT9120 and Rockchip RV1126 and RK3568

Merge tag 'powerpc-5.15-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman: "A bit of a big batch, partly because I didn't send any last week, and also just because the BPF fixes happened to land this week.
Summary:
- Fix a regression hit by the IPR SCSI driver, introduced by the recent addition of MSI domains on pseries.
- A big series including 8 BPF fixes, some with potential security impact and the rest various code generation issues.
- Fix our program check assembler entry path, which was accidentally jumping into a gas macro and generating strange stack frames, which could confuse find_bug().
- A couple of fixes, and related changes, to fix corner cases in our machine check handling.
- Fix our DMA IOMMU ops, which were not always returning the optimal DMA mask, leading to at least one device falling back to 32-bit DMA when it shouldn't.
- A fix for KUAP handling on 32-bit Book3S.
- Fix crashes seen when kdumping on some pseries systems.

powerpc/64s: Fix unrecoverable MCE calling async handler from NMI
The machine check handler is not considered NMI on 64s. The early handler is the true NMI handler, and then it schedules the machine_check_exception handler to run when interrupts are enabled.
This works fine except the case of an unrecoverable MCE, where the true NMI is taken when MSR[RI] is clear, it can not recover, so it calls machine_check_exception directly so something might be done about it.
Calling an async handler from NMI context can result in irq state and other things getting corrupted. This can also trigger the BUG at arch/powerpc/include/asm/interrupt.h:168 BUG_ON(!arch_irq_disabled_regs(regs) && !(regs->msr & MSR_EE));
Fix this by making an _async version of the handler which is called in the normal case, and a NMI version that is called for unrecoverable interrupts.

powerpc/64s: fix program check interrupt emergency stack path
Emergency stack path was jumping into a 3: label inside the __GEN_COMMON_BODY macro for the normal path after it had finished, rather than jumping over it. By a small miracle this is the correct place to build up a new interrupt frame with the existing stack pointer, so things basically worked okay with an added weird looking 700 trap frame on top (which had the wrong ->nip so it didn't decode bug messages either).
Fix this by avoiding using numeric labels when jumping over non-trivial macros.
