Here is v4 of my cleanup series for musb in CPPI DMA mode.
v3 -> v4:
* s/MUSB_CSR0_TXPKTRDY/MUSB_TXCSR_TXPKTRDY/ in patch #4
* s/packet_done/rx_packet_done/ in #5
v2 -> v3:
* Dropped the RXSTALL bit modification from patch #4
* Droped some occasions where musb_ep_select() is not
necessary, in patch #6
* Slightly reworded the commit log of #5
* Added a 7th patch to fix a wrongly indented block
in musb_host.c
v1 -> v2:
* Some commit logs fixed and reworded
* Squashed #6 and #7, as they are basically doing the same
thing
* Added some more occasions where musb_ep_select() was
missing before CSR register access, and added those
hunks to #6 as well.
With this series applied, iperf works correctly with Wifi sticks
connected via USB.
Again, #1 can go via slave-dma.git, and #3 - #6 are potentially
interesting for stable@.
Thanks,
Daniel
