2020-07-17sound: Add an ACPI driver for Maxim MAX98357acSimon Glass
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).

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
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.

2020-02-05sandbox: sound: Handle errors better in sound_beep()Simon Glass
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>
2020-02-05sound: Add a new stop_play() methodSimon Glass
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 Glass
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.

2019-02-20sound: Add support for Intel HDASimon Glass
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 Glass
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>

2018-12-13dm: sound: Use the correct number of channels for soundSimon Glass
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.

2018-12-13dm: sound: Create a uclass for soundSimon Glass
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.

2018-12-13dm: sound: Create a uclass for i2sSimon Glass
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>

2018-12-13dm: sound: Rename samsung_i2s_priv to i2s_uc_privSimon Glass
