This patch series moves the piecewise linear function class from
the Rasberry Pi IPA to libipa so that all IPAs can use it.

First an addition to the geometry header is needed, to add a
floating-point version of the Point class, then the pwl is copied over,
and the Raspberry Pi IPA is converted to use the libipa Pwl class.

Paul Elder (4):
  libcamera: geometry: Add floating-point version of Point class
  ipa: libipa: Copy pwl from rpi
  ipa: libipa: pwl: Clean up Pwl class to match libcamera
  ipa: rpi: controller: Use libipa's Pwl class
