32 * VENC Handle the pixels encoding to the output formats.
33 * We handle the following encodings :
35 * - CVBS Encoding via the ENCI encoder and VDAC digital to analog converter
36 * - TMDS/HDMI Encoding via ENCI_DIV and ENCP
37 * - Setup of more clock rates for HDMI modes
41 * - LCD Panel encoding via ENCL
42 * - TV Panel encoding via ENCT

57 * The ENCI is designed for PAl or NTSC encoding and can go through the VDAC
58 * directly for CVBS encoding or through the ENCI_DVI encoder for HDMI.
59 * The ENCP is designed for Progressive encoding but can also generate
60 * 1080i interlaced pixels, and was initialy desined to encode pixels for
61 * VDAC to output RGB ou YUV analog outputs.
62 * It's output is only used through the ENCP_DVI encoder for HDMI.
63 * The ENCL LVDS encoder is not implemented.
65 * The ENCI and ENCP encoders needs specially defined parameters for each
66 * supported mode and thus cannot be determined from standard video timings.
68 * The ENCI end ENCP DVI encoders are more generic and can generate any timings
69 * from the pixel data generated by ENCI or ENCP, so can use the standard video
70 * timings are source for HW parameters.
