title: MediaTek Media Data Path 3 Tone Curve Conversion

maintainers:
  - Matthias Brugger <matthias.bgg@gmail.com>

description:
  Tone Curve Conversion (TCC) is one of Media Profile Path 3 (MDP3) components.
  It is used to handle the tone mapping of various gamma curves in order to
  achieve HDR10 effects. This helps adapt the content to the color and
  brightness range that standard display devices typically support.
