c5a120b3f0 tegra: sound: Add an I2S driver
Add a driver which supports transmitting digital sound to an audio codec.
This uses fixed parameters as a device-tree binding is not currently
defined.

7b96c6c89a x86: sound: Add sound support for samus (broadwell)
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. The next commit fixes this.

2ca471379b sound: Add support for Intel HDA
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).

d490189865 dm: sound: Create a uclass for sound
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.

e96fa6c911 dm: sound: Create a uclass for i2s
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.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

a77bf70978 sound: Move Samsung-specific code into its own file
The i2s code is in fact Samsung-specific, but there might be other
implementation. Move this code into its own file. This makes it slightly
more obviously how to adjust the code to support another SoC, when someone
takes this task on.

Also drop non-FDT support, since it isn't used on Exynos 5.
