5 drivers

10 ASoC: Add support for Rpi-DAC
11
12 ASoC: Add prompt for ICS43432 codec
13
14 Without a prompt string, a config setting can't be included in a
15 defconfig. Give CONFIG_SND_SOC_ICS43432 a prompt so that Pi soundcards
16 can use the driver.

20 Add IQaudIO Sound Card support for Raspberry Pi
21
22 Set a limit of 0dB on Digital Volume Control
23
24 The main volume control in the PCM512x DAC has a range up to
25 +24dB. This is dangerously loud and can potentially cause massive
26 clipping in the output stages. Therefore this sets a sensible
27 limit of 0dB for this control.
28
29 Allow up to 24dB digital gain to be applied when using IQAudIO DAC+
30
31 24db_digital_gain DT param can be used to specify that PCM512x
32 codec "Digital" volume control should not be limited to 0dB gain,
33 and if specified will allow the full 24dB gain.
34
35 Modify IQAudIO DAC+ ASoC driver to set card/dai config from dt
36
37 Add the ability to set the card name, dai name and dai stream name, from
38 dt config.

42 IQaudIO: auto-mute for AMP+ and DigiAMP+
43
44 IQAudIO amplifier mute via GPIO22. Add dt params for "one-shot" unmute
45 and auto mute.
46
47 Revision 2, auto mute implementing HiassofT suggestion to mute/unmute
48 using set_bias_level, rather than startup/shutdown....
49 "By default DAPM waits 5 seconds (pmdown_time) before shutting down
50 playback streams so a close/stop immediately followed by open/start
51 doesn't trigger an amp mute+unmute."
52
53 Tested on both AMP+ (via DAC+) and DigiAMP+, with both options...
54
55 dtoverlay=iqaudio-dacplus,unmute_amp
56 "one-shot" unmute when kernel module loads.
57
58 dtoverlay=iqaudio-dacplus,auto_mute_amp
59 Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
60 when ALSA device closed. (Re-opening the device within the 5 second close
61 window, will cancel mute.)
62
63 Revision 4, using gpiod.
64
65 Revision 5, clean-up formatting before adding mute code.
66 - Convert tab plus 4 space formatting to 2x tab
67 - Remove '// NOT USED' commented code
68
69 Revision 6, don't attempt to "one-shot" unmute amp, unless card is
70 successfully registered.

85 Added support for HiFiBerry DAC+
86
87 The driver is based on the HiFiBerry DAC driver. However HiFiBerry DAC+ uses
88 a different codec chip (PCM5122), therefore a new driver is necessary.
89
90 Add support for the HiFiBerry DAC+ Pro.
91
92 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.
93
94 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.
95
96 Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+
97
98 24db_digital_gain DT param can be used to specify that PCM512x
99 codec "Digital" volume control should not be limited to 0dB gain,
100 and if specified will allow the full 24dB gain.
101
102 Add dt param to force HiFiBerry DAC+ Pro into slave mode
103
104 "dtoverlay=hifiberry-dacplus,slave"
105
106 Add 'slave' param to use HiFiBerry DAC+ Pro in slave mode,
107 with Pi as master for bit and frame clock.

115 ASoC: pcm512x: revert downstream changes
116
117 This partially reverts commit 185ea05465aac8bf02a0d2b2f4289d42c72870b7
118 which was added by https://github.com/raspberrypi/linux/pull/1152
119
120 The downstream pcm512x changes caused a regression, it broke normal
121 use of the 24bit format with the codec, eg when using simple-audio-card.
122
123 The actual bug with 24bit playback is the incorrect usage
124 of physical_width in various drivers in the downstream tree
125 which causes 24bit data to be transmitted with 32 clock
126 cycles. So it's not the pcm512x that needs fixing, it's the
127 soundcard drivers.

189 New AudioInjector.net Pi soundcard with low jitter audio in and out.
190
191 Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile.
192 Adds the dts overlay and updates the Makefile and README.
193 Updates the relevant defconfig files to enable building for the Raspberry Pi.
194 Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions.
195
196 Added support for headphones, microphone and bclk_ratio settings.
197
198 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.

534 ASoC: Add generic RPI driver for simple soundcards.
535
536 The RPI simple sound card driver provides a generic ALSA SOC card driver
537 supporting a variety of Pi HAT soundcards. The intention is to avoid
538 the duplication of code for cards that can't be fully supported by
539 the soc simple/graph cards but are otherwise almost identical.
540
541 This initial commit adds support for the ADAU1977 ADC, Google VoiceHat,
542 HifiBerry AMP, HifiBerry DAC and RPI DAC.

564 ASoC: Create a generic Pi Hat WM8804 driver
565
566 Reduce the amount of duplicated code by creating a generic driver for
567 Pi Hat digi cards using the WM8804 codec.
568
569 This replaces the
570 Allo DigiOne, Hifiberry Digi/Pro, JustBoom Digi and IQAudIO Digi
571 dedicate soundcard drivers with a generic driver.
572
573 There are no significant changes to the runtime behavior of the drivers
574 and end users should not have to change any configuration settings
575 after upgrading.
576
577 Minor changes
578 * Check the return value of snd_soc_component_update_bits
579 * Added some pr_debug tracing
580 * Various checkpatch tidyups
581 * Updated allodigi-one to use use 128FS at > 96 Khz. This appears to
582 be an omission in the original driver code so followed the Hifiberry
583 DAC driver approach.

615

617
618 This hardware provides multiple audio I/O capabilities to the RPi.
619 The codec connects to the RPi's SoC through the I2S Bus.
620
621 The following devices can be connected through a 3.5mm jack
622 1. Line-In: Plain old audio in from mobile phones, PCs, etc.,
623 2. Mic-In: Connect a microphone
624 3. Line-Out: Connect the output to a speaker
625 4. Headphones: Connect a Headphone w or w/o microphones
626
627 Multiple Inputs:
628 It supports the following combinations
629 1. Two stereo Line-Inputs and a microphone
630 2. One stereo Line-Input and two microphones
631 3. Two stereo Line-Inputs, a microphone and
632 one mono line-input (with h/w hack)
633 4. One stereo Line-Input, two microphones and
634 one mono line-input (with h/w hack)
635

654 ASoC: hifiberry_dacplusadc: fix DAI link setup
655
656 The driver only defines a single DAI link and the code that tries
657 to setup the second (non-existent) DAI link looks wrong - using dmic
658 as a CPU/platform driver doesn't make any sense.
659
660 The DT overlay doesn't define a dmic property, so the code was never
661 executed (otherwise it would have resulted in a memory corruption).
662
663 So drop the offending code to prevent issues if a dmic property
664 should be added to the DT overlay.

973 44.1kHz sound to see the effect, but in some configurations the codec
974 can lock into the wrong state and always get some rates wrong.
