/**
|
||
* 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.
