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