Changes (by buytenh):

  * status:  new => closed
  * resolution:  => fixed


Comment:

 The mmp2-i2s driver forgot to set the MSB when doing writes to the
 {RX,TX}_SP_CTRL registers, causing those writes not to stick.  Should be
 fixed by the following commit on the audio-wip branch of the xo1.75
 -kernel-bringup repository:

 commit cfd457192dc0b5030f6e5335410a898b65e75716
 Author: Lennert Buytenhek <buytenh at wantstofly.org>

     mmp2-i2s: Always perform SP_CTRL writes with the MSB set.
