sound: Add uclass operations for beeping

2019-02-20T07:27:08Z

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 Reviewed-by: Bin Meng

sandbox: pch: Add a test for the PCH uclass

2019-02-20T07:26:36Z

This uclass currently has no tests. Add a sandbox driver and some simple tests to provide basic coverage. Signed-off-by: Simon Glass Reviewed-by: Bin Meng [bmeng: Use "sandbox,pch" for the compatible string, for consistency] Signed-off-by: Bin Meng

sandbox: Add a note about the growing state_info struct

2019-02-20T07:25:29Z

This struct is getting larger and in some cases is being used for things which would be better put into a driver. For example hwspinlock is not used outside of sandbox_hwspinlock.c. Add a note to encourage people to put things elsewhere. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

sandbox: add memset_io(..), memcpy_fromio(..) and memcpy_toio(..)

2019-01-15T00:47:13Z

These functions could be used by drivers. Signed-off-by: Christian GMEINER Reviewed-by: Simon Glass

dm: sandbox: Allow selection of sample rate and channels

2018-12-13T23:37:09Z

At present these parameters are hard-coded in the sdl interface code. Allow them to be specified by the driver instead. Signed-off-by: Simon Glass

dm: sound: Complete migration to driver model

2018-12-13T23:36:41Z

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

dm: sandbox: sound: Convert to use driver model

2018-12-13T23:36:30Z

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. Signed-off-by: Simon Glass

dm: sound: Create a uclass for sound

2018-12-13T23:32:49Z

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

dm: sound: Create a uclass for i2s

2018-12-13T23:32:49Z

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

dm: sound: Create a uclass for audio codecs

2018-12-13T23:32:49Z

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. Signed-off-by: Simon Glass
