%description
Configuration for the Sony IMX471 MIPI camera found behind the Intel IPU7 in
the ThinkPad X1 Carbon Gen 14 and ThinkPad X9, for use with libcamera's
software ISP:

- a software ISP tuning file (black level and a generic colour correction
  matrix). It is installed in /etc, which libcamera searches before
  /usr/share: remove this package once libcamera ships its own imx471.yaml.
- a udev rule that raises the sensor's vertical blanking for 25 fps, because
  the driver defaults to 57.8 fps (17 ms maximum exposure) and the software
  ISP never changes it.
