+/* 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
