Gregory Nutt 1f2428c087 WM8904: Ad the MCLK frequency to the interface definition. The WM8904 driver needs to know this frequency in order to configure the FLL to generate the correct bitrate 2014-08-01 18:37:56 -06:00
Gregory Nutt e59bb45b33 Add debug logic to dump WM8904 registers 2014-08-01 18:07:20 -06:00
Gregory Nutt e214382264 Audio: Change how the end of the audio stream is detected by the leaf audio component. This used by be done by looking for the first partial buffer. That does not work with the in-place sub-sampling performed by the PCM decoder: That always reduces the size of the buffer so that all buffers only partially filled by the time they get to the leaf. Now, a flag is set in the audio buffer flags set to indicate the final buffer in the stream. 2014-07-31 16:36:09 -06:00
