usb: do explicit unaligned accesses

2012-09-20T22:05:00Z

usb_hub_descriptor has to be packed as it's used for communication with the device. Member wHubCharacteristics violates the natural alignment rules. Use explicit unaligned access functions for this member. Fixes ARMv7 traping while using USB. v2: fix typo found by Thomas Langer v3: rebased on top of u-boot-usb/master Signed-off-by: Lucas Stach

MUSB driver: Timeout is never detected as the while loop does not end

2012-09-01T14:21:53Z

Timeout variable is decremented once more when while condition is not met. Following "if" does not detect correctly that timeout has occurred. Because of this bug the "usb start" command on AM335X-EVM board did not detect correctly that USB device was not attached. timeout = musb_cfg.timeout; while (timeout--) if (readb(&musbr->devctl) & MUSB_DEVCTL_HM) break; /* if musb core is not in host mode, then return */ if (!timeout) return -1; Signed-off-by: Matej Franceskin CC: Marek Vasut ?

USB: Fix strict aliasing in ohci-hcd

2012-09-01T14:21:53Z

commit 5f6aa03fda2a0a79940765865c1e4266be8a75f8 USB: Fix complaints about strict aliasing in OHCI-HCD tried to fix this, but gcc4.4 still complains. So, this patch basically reverts the above and does a simpler fix. also, the above commit incorrectly changed /* corresponds to data_buf[4-7] */ datab [1] = 0; to /* corresponds to databuf.u8[4-7] */ databuf.u8[1] = 0; This patch also fixes that.

ehci: Optimize qTD allocations

2012-09-01T14:21:52Z

Relax the qTD transfer alignment constraints in order to need less qTDs for buffers that are aligned to 512 bytes but not to pages. Signed-off-by: Benoît Thébaudeau Cc: Marek Vasut Cc: Ilya Yanok Cc: Stefan Herbrechtsmeier

ehci-hcd: Boost transfer speed

2012-09-01T14:21:52Z

This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid software and transfer splitting overhead so as to make transfers as fast as possible. The only drawback is a call to memalign. However, this is fast compared to the transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the worst case for a transfer length of 65535 packets of 512 bytes. Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was very significant (several times faster), which is really appreciable when accessing large files.

ehci: Fail for multi-transaction interrupt transfers

2012-09-01T14:21:51Z

Interrupt transfers requiring several transactions are not supported by submit_int_msg() because bInterval is ignored. This patch returns a failure code and prints an error message in this case. Signed-off-by: Benoît Thébaudeau Cc: Marek Vasut Cc: Ilya Yanok Cc: Stefan Herbrechtsmeier
