35 * Juli does not use the standard ICE1724 clock scheme. Juli's ice1724 chip is
36 * supplied by external clock provided by Xilinx array and MK73-1 PLL frequency
37 * multiplier. Actual frequency is set by ice1724 GPIOs hooked to the Xilinx.
38 *
39 * The clock circuitry is supplied by the two ice1724 crystals. This
40 * arrangement allows to generate independent clock signal for AK4114's input
41 * rate detection circuit. As a result, Juli, unlike most other
42 * ice1724+ak4114-based cards, detects spdif input rate correctly.
43 * This fact is applied in the driver, allowing to modify PCM stream rate
44 * parameter according to the actual input rate.
45 *
46 * Juli uses the remaining three stereo-channels of its DAC to optionally
47 * monitor analog input, digital input, and digital output. The corresponding
48 * I2S signals are routed by Xilinx, controlled by GPIOs.
49 *
50 * The master mute is implemented using output muting transistors (GPIO) in
51 * combination with smuting the DAC.
52 *
53 * The card itself has no HW master volume control, implemented using the
54 * vmaster control.
