/* PHASE 22 overview:
* Audio controller: VIA Envy24HT-S (slightly trimmed down version of Envy24HT)
* Analog chip: AK4524 (partially via Philip's 74HCT125)
* Digital receiver: CS8414-CS (not supported in this release)
*
* Envy connects to AK4524
* - CS directly from GPIO 10
* - CCLK via 74HCT125's gate #4 from GPIO 4
* - CDTI via 74HCT125's gate #2 from GPIO 5
* CDTI may be completely blocked by 74HCT125's gate #1 controlled by GPIO 3
