  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.
