[PATCH] USB: more omap_udc updates (dma and omap1710)
More omap_udc updates:
* OMAP 1710 updates
- new UDC bit for clearing endpoint toggle, affecting CLEAR_HALT
- new OTG bits affecting wakeup
* Fix the bug Vladimir noted, that IN-DMA transfer code path kicks in
for under 1024 bytes (not "up to 1024 bytes")
* Handle transceiver setup more intelligently
- use transceiver whenever one's available; this can be handy
for GPIO based, loopback, or transceiverless configs
- cleanup correctly after the "unrecognized HMC" case
* DMA performance tweaks
- allow burst/pack for memory access
- use 16 bit DMA access most of the time on TIPB
* Add workarounds for some DMA errata (not observed "in the wild"):
- DMA CSAC/CDAC reads returning zero
- RX/TX DMA config registers bit 12 always reads as zero (TI patch)
* More "sparse" warnings removed, notably "changing" the SETUP packet
to return data in USB byteorder (an API change, null effect on OMAP
except for these warnings).
