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 initially designed 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.
