%description
Out-of-tree build of the Raspberry Pi downstream IMX477 image-sensor driver,
ported to build against mainline-based Fedora aarch64 kernels (e.g. the
pbrobinson/a64-kernel COPR), so the Raspberry Pi High Quality Camera works on
Fedora. Used by the OpenFlexure microscope port. Pair with "dtoverlay=imx477"
and FirmwareDT=True to enable the camera.

# Shared, kernel-independent files that the kmod-<kernel> subpackages require.
