/**
* DOC: Video Encoder
*
* VENC Handle the pixels encoding to the output formats.
* We handle the following encodings :
*
* - CVBS Encoding via the ENCI encoder and VDAC digital to analog converter
* - TMDS/HDMI Encoding via ENCI_DIV and ENCP
* - Setup of more clock rates for HDMI modes
*
* What is missing :
*
* - LCD Panel encoding via ENCL
* - TV Panel encoding via ENCT
*
* VENC paths :
*
* .. code::
*

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