| description: |
| Provides voltage source for DCC lines available on HDMI connector. When |
| there is no power provided for DDC epprom, some TV-sets do not pulls up |
| HPD (hot plug detect) line, what causes HDMI block to stay turned off. |
| When provided, the regulator allows TV-set correctly signal HPD event. |
