These are all moving to meta-extras. Ideally in the future machines such as these will be maintained to topic specific layers as we move to a more layer oriented model.

-Subject: [PATCH] USB: musb: rewrite host periodic endpoint allocation
-
-The current MUSB host code doesn't make use of all the available
-FIFOs in for periodic transfers since it wrongly assumes the RX
-and TX sides of any given hw_ep always share one FIFO.
-
-Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep'
-to check the endpoint's business; get rid of the now-unused 'periodic'
-array in the 'struct musb'. Also optimize a loop induction variable
-in the endpoint lookup code.
-
-(Based on a previous patch from Ajay Kumar Gupta <ajay.gupta-l0cyMroinI0@public.gmane.org>)
