Fri Jan 18 07:05:43 CET 2008
This patch adds additional output to the /proc codec#X info.
The following pieces of information are added to the output:
- Balanced, L/R swap, trigger, impedance sense pin capabilities
- Vref pin capabilities
- Current Vref pin widget control setting
- Default configuration association, sequence, and misc bit test
- EAPD/BTL bits conveying balanced mode, EAPD, and L/R swap
- Power state modified to show state name as well as setting vs actual value
- GPIO parameter output on Audio Function Group, including enumeration of IO
pins which are indicated present (Any I and O pins are not output at this
time)
- Stripe and L/R swap widget capabilities
- All digital converter bits: enable, validity, validity config, preemphasis,
copyright, non-audio, professional, generation level, and content category
- Converter stream and channel values for in/out widgets
- SDI select value for in widgets
- Unsolicited response widget capability tag and enabled bit
- Delay widget capability value
- Processing widget capability benign bit and number of coefficients
- Realtek Define Registers: processing coefficient, coefficient index
