1 | * Texas Instruments TVP514x video decoder | ||
2 | |||
3 | The TVP5146/TVP5146m2/TVP5147/TVP5147m1 device is high quality, single-chip | ||
4 | digital video decoder that digitizes and decodes all popular baseband analog | ||
5 | video formats into digital video component. The tvp514x decoder supports analog- | ||
6 | to-digital (A/D) conversion of component RGB and YPbPr signals as well as A/D | ||
7 | conversion and decoding of NTSC, PAL and SECAM composite and S-video into | ||
8 | component YCbCr. | ||

10 | Required Properties : | ||
11 | - compatible : value should be either one among the following | ||
12 | (a) "ti,tvp5146" for tvp5146 decoder. | ||
13 | (b) "ti,tvp5146m2" for tvp5146m2 decoder. | ||
14 | (c) "ti,tvp5147" for tvp5147 decoder. | ||
15 | (d) "ti,tvp5147m1" for tvp5147m1 decoder. | ||
