18 * DOC: Video Encoder
19 *
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
31 *
32 * VENC paths :
33 *
34 * .. code::

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.
