The in-tree 7.2 CVS driver we ship as the intel-cvs DKMS module requests its "wake" line with devm_gpiod_get(). On the Dell XPS 14 DA14260 that pin (\_SB.GPI1 20) is the shared GpioIo the four CS35L57 amplifiers read their speaker ID from, so with this package installed every cs35l56 probe fails with "error -EBUSY: Failed to get spk-id-gpios" and the machine has no sound card. Carry Junjie Cao's upstream fix, "media: i2c: cvs: Get the wake IRQ without claiming the GPIO" (Cc: stable, Fixes: 8e2b43d2c10b), applied to the downloaded intel-cvs-core.c in prepare(). makepkg symlinks plain downloads into srcdir and patch refuses symlinks, so the file is copied first. Drop the patch once the stable tag we fetch from contains the fix. Link: https://github.com/thesofproject/sof/issues/11152 Link: https://bugzilla.redhat.com/show_bug.cgi?id=2529031

# Intel CVS (Computer Vision Sensing) CSI-2 bridge driver.

#
|
|
# Copy of the in-tree Linux 7.2 driver (drivers/media/i2c/cvs) plus the
|
|
# upstream wake-IRQ fix carried by the PKGBUILD, built out of tree so it
|
|
# exists on every 7.2+ kernel regardless of the kernel's Kconfig.
|
|
# Arch-derived configs cannot enable VIDEO_INTEL_CVS at all: it lives under
|
|
# the "Miscellaneous helper chips" menu, which is hidden by
|
|
# MEDIA_HIDE_ANCILLARY_SUBDRV unless CONFIG_EXPERT is set.
|
|
#
|
|
# 7.2's ipu-bridge inserts the CVS device between the sensor and the IPU
|
|
# CSI2 receiver, so the IPU only sees the sensor once a driver registers
|
|
# this V4L2 bridge sub-device. Kernels before 7.2 keep using the legacy
|
|
# misc driver from vision-drivers (see dkms-vision-drivers.conf).
