For snow the codec is at address 0x11 on the i2c bus, in 7-bit format.
The device tree and code are in 8-bit format (i.e. shifted left one bit).
Fix both. Fix pit in a similar way.

Changes in v2:
- Add fix for pit and pi also
- Fix up tabs in this commit instead of the later one

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.

This structure contains information that is likely needed by any i2s
driver so it seems useful to attach it to the (forthcoming) i2c uclass.
For now, just rename it.

An audio codec provides a way to convert digital data to sound and vice
versa. Add a simple uclass which just supports setting the parameters for
the codec.

To: u-boot
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.

At present we use a single buffer for sound which means we cannot be
playing one sound while queueing up the next. This wouldn't matter except
that a long sound (more than a second) has to be created as a single
buffer, thus using a lot of memory. To better mimic what real sound
drivers do, add support for double buffering in sandbox.

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.

The current dev_read...() functions use s32 and u32 which are convenient
for device tree but not so useful for normal code, which often wants to
use normal integers for values.
Add a helper which supports returning an unsigned int. Also add signed
versions of the unsigned readers.

Allow setting the i2s pinmux correctly on exyno5420 so that i2c can be
used on that SoC. Also rename EXYNOS_AUDSS to something consistent with
other naming.

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.

Update sandbox's device tree and config to use driver model for sound. Use
the double buffer for sound output so that we don't need to wait for the
sound to complete before returning.

All users of sound are converted to use driver model. Drop the old code
and the CONFIG_DM_SOUND option.
Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v2:
- Drop CONFIG_DM_SOUND from all defconfig files
- Fix up sandbox files to remove old code
- Update the rest of the samsung boards
- Remove unused sandbox code also
- Drop patches previously applied

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.
The fix in a previous commit was correct for sandbox but not for other
boards.

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.

The current ID enums start from 1 but there does not seem to be any reason
that they cannot start with 0. Adjust the code to avoid the +1 in
codec_init().

The current dev_read...() functions use s32 and u32 which are convenient
for device tree but not so useful for normal code, which often wants to
use normal integers for values.
Add a helper which supports returning an unsigned int. Also add signed
versions of the unsigned readers.

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.

At present we use a single buffer for sound which means we cannot be
playing one sound while queueing up the next. This wouldn't matter except
that a long sound (more than a second) has to be created as a single
buffer, thus using a lot of memory. To better mimic what real sound
drivers do, add support for double buffering in sandbox.

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.

An audio codec provides a way to convert digital data to sound and vice
versa. Add a simple uclass which just supports setting the parameters for
the codec.

This structure contains information that is likely needed by any i2s
driver so it seems useful to attach it to the (forthcoming) i2c uclass.
For now, just rename it.

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.

For snow the codec is at address 0x11 on the i2c bus, in 7-bit format.
The device tree and code are in 8-bit format (i.e. shifted left one bit).
Fix both. Fix pit in a similar way.
