Add IQaudIO Sound Card support for Raspberry Pi
Set a limit of 0dB on Digital Volume Control The main volume control in the PCM512x DAC has a range up to +24dB. This is dangerously loud and can potentially cause massive clipping in the output stages. Therefore this sets a sensible limit of 0dB for this control. Allow up to 24dB digital gain to be applied when using IQAudIO DAC+ 24db_digital_gain DT param can be used to specify that PCM512x codec "Digital" volume control should not be limited to 0dB gain, and if specified will allow the full 24dB gain. Modify IQAudIO DAC+ ASoC driver to set card/dai config from dt Add the ability to set the card name, dai name and dai stream name, from dt config.

Revision 2, auto mute implementing HiassofT suggestion to mute/unmute using set_bias_level, rather than startup/shutdown.... "By default DAPM waits 5 seconds (pmdown_time) before shutting down playback streams so a close/stop immediately followed by open/start doesn't trigger an amp mute+unmute." Tested on both AMP+ (via DAC+) and DigiAMP+, with both options... dtoverlay=iqaudio-dacplus,unmute_amp "one-shot" unmute when kernel module loads. dtoverlay=iqaudio-dacplus,auto_mute_amp Unmute amp when ALSA device opened by a client. Mute, with 5 second delay when ALSA device closed. (Re-opening the device within the 5 second close window, will cancel mute.) Revision 4, using gpiod. Revision 5, clean-up formatting before adding mute code. - Convert tab plus 4 space formatting to 2x tab - Remove '// NOT USED' commented code Revision 6, don't attempt to "one-shot" unmute amp, unless card is successfully registered.

However HiFiBerry DAC+ uses a different codec chip (PCM5122), therefore a new driver is necessary. Add support for the HiFiBerry DAC+ Pro. The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators. An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame. Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+ 24db_digital_gain DT param can be used to specify that PCM512x codec "Digital" volume control should not be limited to 0dB gain, and if specified will allow the full 24dB gain. Add dt param to force HiFiBerry DAC+ Pro into slave mode "dtoverlay=hifiberry-dacplus,slave" Add 'slave' param to use HiFiBerry DAC+ Pro in slave mode, with Pi as master for bit and frame clock.

The actual bug with 24bit playback is the incorrect usage of physical_width in various drivers in the downstream tree which causes 24bit data to be transmitted with 32 clock cycles. So it's not the pcm512x that needs fixing, it's the soundcard drivers.

Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile. Adds the dts overlay and updates the Makefile and README. Updates the relevant defconfig files to enable building for the Raspberry Pi. Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions. Added support for headphones, microphone and bclk_ratio settings. This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.
