* 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.

* researching and fixing the input monitors
