/* PHASE 22 overview:
 *   Audio controller: VIA Envy24HT-S (slightly trimmed down Envy24HT, 4in/4out)
 *   Analog chip: AK4524 (partially via Philip's 74HCT125)
 *   Digital receiver: CS8414-CS (supported in this release)
 *              PHASE 22 revision 2.0 and Terrasoniq/Musonik TS22PCI have CS8416
 *              (support status unknown, please test and report)
 *
 *   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
 */

/* PHASE 28 overview:
 *   Audio controller: VIA Envy24HT (full untrimmed version, 4in/8out)
 *   Analog chip: WM8770 (8 channel 192k DAC, 2 channel 96k ADC)
 *   Digital receiver: CS8414-CS (supported in this release)
