  20  * VENC Handle the pixels encoding to the output formats.
  21  * We handle the following encodings :
  22  *
  23  * - CVBS Encoding via the ENCI encoder and VDAC digital to analog converter
  24  * - TMDS/HDMI Encoding via ENCI_DIV and ENCP
  25  * - Setup of more clock rates for HDMI modes
  26  *
  27  * What is missing :
  28  *
  29  * - LCD Panel encoding via ENCL
  30  * - TV Panel encoding via ENCT

  44  *
  45  * The ENCI is designed for PAl or NTSC encoding and can go through the VDAC
  46  * directly for CVBS encoding or through the ENCI_DVI encoder for HDMI.
  47  * The ENCP is designed for Progressive encoding but can also generate
  48  * 1080i interlaced pixels, and was initialy desined to encode pixels for
  49  * VDAC to output RGB ou YUV analog outputs.
  50  * It's output is only used through the ENCP_DVI encoder for HDMI.
  51  * The ENCL LVDS encoder is not implemented.
  52  *
  53  * The ENCI and ENCP encoders needs specially defined parameters for each
  54  * supported mode and thus cannot be determined from standard video timings.
  55  *
  56  * The ENCI end ENCP DVI encoders are more generic and can generate any timings
  57  * from the pixel data generated by ENCI or ENCP, so can use the standard video
  58  * timings are source for HW parameters.
