Rebase onto Arch's 7.2.4.arch1-2 (config byte-identical to Arch stock apart from the rustc/bindgen version strings). Patches 0020, 0028 and 0029 apply unchanged at fuzz 0; the intel_quirks.c 1028:* entries and the QUIRK_DISABLE_EDP_PANEL_REPLAY consumer are as before. New patches: - 0030 media: i2c: cvs: Get the wake IRQ without claiming the GPIO (Junjie Cao, Cc: stable, Fixes: 8e2b43d2c10b). The 7.2 CVS camera driver claimed its wake line with devm_gpiod_get(); on the Dell XPS 14 DA14260 that pin is the GpioIo the four CS35L57 amplifiers read their speaker ID from, so every cs35l56 probe failed with -EBUSY and no sound card existed. The Arch config does not build the in-tree driver, so this is carried for parity with the DKMS copy in intel-ipu7-camera (omarchy-pkgs#418), which is where the fix takes effect on shipped systems. - 0031 spi: cs42l43: Workaround for ACPI with wrong spk-id-gpios (Richard Fitzgerald). Reads each speaker-ID pin of a multi-pin GpioIo individually on cs42l43 SPI sidecar-amp systems such as the XPS 13 DX13260, where the amps otherwise cannot select their tuning (omarchy#10987, omarchy#11374). Tested on an XPS 14 DA14260 together with intel-ipu7-camera 1.0.6-2: the sof-soundwire card is created and all four amplifiers load their cs35l57-b2-dsp1-misc-10280db9-spkid0 tuning.

What
7.2.4.arch1-2(latest core).config.x86_64is Arch stock; the only differences from our 7.2.3 config are the rustc/bindgen version strings. Kernel tarball and Arch patch signatures verified with GPG during the build.intel_quirks.cgained no new1028:*entries and theQUIRK_DISABLE_EDP_PANEL_REPLAYconsumer inintel_psr.cis unchanged.media: i2c: cvs: Get the wake IRQ without claiming the GPIO(Junjie Cao, Cc: stable,Fixes: 8e2b43d2c10b, patchwork).spi: cs42l43: Workaround for ACPI with wrong spk-id-gpios(Richard Fitzgerald, Cirrus; not yet on a public list).Why
On the Dell XPS 14 DA14260 the four CS35L57 SoundWire amplifiers read their speaker ID from one shared GpioIo (
\_SB.GPI1pin 20). The 7.2 in-tree Intel CVS camera driver requests its "wake" line withdevm_gpiod_get()on that same pin, so with it loaded every amp probe fails:and the machine has no sound card.
/sys/kernel/debug/gpioshows the line held aswake ... IRQ ACTIVE LOW. 0030 is the upstream fix. Note the Arch config cannot build the in-tree CVS driver, so on this package the patch is source parity only: the copy that actually runs is the DKMS module in intel-ipu7-camera, fixed in #418. Carrying it here keeps the two in step and covers any future config that enables the driver.0031 is unrelated to the XPS 14 and only affects
spi-cs42l43systems (XPS 13 DX13260 with SPI sidecar amps), where the amps fail to read their tuning IDs today (omacom/omarchy#10987, omacom/omarchy#11374).Testing
Built on a clean Arch container. Installed on an XPS 14 DA14260 together with intel-ipu7-camera 1.0.6-2 from #418 and rebooted into
7.2.4-arch1-1-ptl:aplay -llists thesof-soundwirecard with the Speaker device.cs35l57-b2-dsp1-misc-10280db9-spkid0-*.binand report firmware v4.5.9; no-EBUSYin the log.intel_cvs(DKMS, patched) binds and the camera still probes.Panel Self Refresh remains broken on this platform as before; nothing here changes the display patches.
