Simon Glass	2850266965	sound: Add uclass operations for beeping ... 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.

Simon Glass	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. Signed-off-by: Simon Glass <sjg@chromium.org>	2018-12-13 16:32:49 -07:00
