2020-07-17sound: Add an ACPI driver for Maxim MAX98357acSimon Glass3-0/+171
This chip is used on coral and we need to generate ACPI tables for sound to make it work. Add a driver that does just this (i.e. at present does not actually support playing sound).

2020-02-06dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-02-06sandbox: sound: Handle errors better in sound_beep()Simon Glass1-1/+4
At present an error does not stop the sound-output loop. This is incorrect since nothing can be gained by trying to continue. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-06sound: Add a new stop_play() methodSimon Glass2-1/+31
At present there is no positive indication that U-Boot has finished sending sound data. This means that it is not possible to power down an audio codec, for example. Add a new method that is called once all sound data has been sent. Add a new method for this, called when the sound_play() call is done. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-02-20x86: sound: Add sound support for samus (broadwell)Simon Glass2-1/+66
Add a sound driver for samus which ties together the audio codec and I2S controller. For now broadwell_sound is commented out in the makefile since we cannot compile it without sound support enabled.

2019-02-20sandbox: sound: Silence sound for testingSimon Glass1-3/+22
When testing the sound system we don't need the hear the beeps. The testing works by checking the data that would be emitted. Add a device-tree property to silence the sound, and enable it for testing. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-02-20sound: Add support for Intel HDASimon Glass3-0/+566
The Intel High-definition Audio is a newer-generation audio system which provides for transfer of a large number of audio stream, each containing up to 16 channels. Add support for HDA as a library which can be used by other drivers. U-Boot currently uses only two channels (stereo).

2019-02-20sound: Add uclass operations for beepingSimon Glass2-4/+76
Some audio codecs such as Intel HDA do not need to use digital data to play sounds, but instead have a way to emit beeps. Add this interface as an option. If the beep interface is not supported, then the sound uclass falls back to the I2S interface. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-02-20sound: Mark sound_setup() as optionalSimon Glass1-1/+1

2018-12-14dm: sound: Use the correct number of channels for soundSimon Glass2-5/+8
At present the 'beep' sound generates a waveform for only one channel even if two are being used. This means that the beep is twice the frequency it should be. Correct this by making it a parameter.

Update snow's device tree and config to use driver model for sound. Also update the others as best we can. Spring does not appear to have audio support in the kernel. The smdk5250 and smdk5420 boards use a wolfson codec which I cannot test with. So the only boards that is tested and known to work are snow, pit and pi. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-12-14dm: sound: Create a uclass for soundSimon Glass3-0/+195
The sound driver pulls together the audio codec and i2s drivers in order to actually make sounds. It supports setup() and play() methods. The sound_find_codec_i2s() function allows locating the linked codec and i2s devices. They can be referred to from uclass-private data. Add a uclass and a test for sound. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-12-14dm: sound: Create a uclass for i2sSimon Glass3-1/+85
The i2s bus is commonly used with audio codecs. It provides a way to stream digital data sychronously in both directions. U-Boot only supports audio output, so this uclass is very simple, with a single tx_data() method. Add a uclass and a test for i2s. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-12-14dm: sound: Create a uclass for audio codecsSimon Glass3-0/+82

2018-12-14dm: sound: Rename samsung_i2s_priv to i2s_uc_privSimon Glass2-7/+7

2018-12-14dm: sound: Create an option to use driver model for soundSimon Glass1-0/+6
The U-Boot sound system provides basic support for beeping. At present it does not use driver model, but it needs to be converted. Add an option to enable driver model for sound. For now it is not connected to anything. Future work will add drivers which use this option. It will then be removed once everything is converted. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-12-14dm: sound: exynos: Correct codec bus addressesSimon Glass1-2/+1
