Simon Glass	f987177db9	dm: sound: Use the correct number of channels for sound ... 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.

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
