I enabled all CONFIG_PINCTRL_* below the Intel sub-menu as modules now. Let's see what is needed. It is compiling.
You mean whether I had a look at "lsmod" of a distribution kernel, first? Yes, I did. I also know that I can search with "/" inside menuconfig. In addition, I also run "egrep --recursive --include='Makefile' -i -e 'CONFIG.*<name-of-the-module>.*\.o' /usr/src/linux" to find the CONFIG option which is responsible for building the object file of the module for any module which was reported by "lsmod". I enabled all these CONFIG options as modules (=m) in order to have them (just to be on the safe side). I will deactivate any superfluous module later. Unfortunately, if something is statically built into the distribution kernel like PINCTRL (see above), "lsmod" does not report it.

I actually did that, but for 6.11.8 and I was under the impression to have enabled it. For some reason, sine version 6.12.1 IPU6 has started to depend on ARCH_HAS_DMA_OPS which is only implicitly enabled if one enables GART_IOMMU or XEN. IMHO, this feels like a regression bug, because GART_IOMMU is for AMD and I don't need Xen guest support. I reported that issue upstream. Anyway, I enabled Xen guest support (as a work-around) and re-enabled IPU6 afterwards.

I have also enabled that as a module now (just to be save). It is compiling.

Yes, I did. If you have a look at the dmesg output for the distribution kernel, you'll find | Code: | Loading firmware: intel/sof-ipc4/mtl/sof-mtl.ri
Loading firmware: intel/sof-ace-tplg/sof-hda-generic-2ch.tplg
Loading firmware: intel/sof-ipc4/mtl/sof-mtl.ri
sof-audio-pci-intel-mtl 0000:00:1f.3: Loaded firmware library: ADSPFW, version: 2.11.1.1
sof-audio-pci-intel-mtl 0000:00:1f.3: Booted firmware version: 2.11.1.1
Loading firmware: intel/sof-ace-tplg/sof-hda-generic-2ch.tplg |
Sound works with the distribution kernel. So probably something is missing again which may be statically compiled into the distribution kernel and hence is not reported by "lsmod".

I enabled everything as a module (just to be on the safe side.) Additionally, I enabled everything as a module with "ELAN" in its name, because the distribution kernel reported something by that name. I also enabled everything as modules below "special HID devices". It's compiling.

OK, even though MSI is disabled for the audio controller? |

| For the sake of completeness: i2cdetect for 6.12.1 distribution kernel: https://pastebin.com/eeGGhUu4 But I don't know how to interpret the output. |

I don't know if this is sufficient (unfortunately I can't test it, due to the lack of a notebook with such a PCI crontroller) ... maybe there is a reason why it is statically built into our dist-kernel.
But what comes to my mind: If you boot an Ubuntu LiveCD and check with “lsmod” you will see more there, because Ubuntu has much more built in as <M>odule (AFAIK also pinctrl and designware).

I guess it changes if we have all SOF-firmware in the kernel (and then no -2 error code while loading; saying it is missed).
