- * Terminology:
- * DAS: Digital audio switch (HW module controlled by this driver)
- * DAP: Digital audio port (port/pins on Tegra device)
- * DAC: Digital audio controller (e.g. I2S or AC97 controller elsewhere)
- *
- * The Tegra DAS is a mux/cross-bar which can connect each DAP to a specific
- * DAC, or another DAP. When DAPs are connected, one must be the master and
- * one the slave. Each DAC allows selection of a specific DAP for input, to
- * cater for the case where N DAPs are connected to 1 DAC for broadcast
- * output.
- *
- * This driver is dumb; no attempt is made to ensure that a valid routing
- * configuration is programmed.
