2015-03-24staging: octeon-usb: never retry after xacterrAaro Koskinen1-33/+5
Never retry after xacterr. The DMA engine cannot handle that properly and may result in wrong transfer count and hang. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-24staging: octeon-usb: program DMA engine based on transfer directionAaro Koskinen1-7/+7

2015-03-24staging: octeon-usb: use __BITFIELD_FIELDAaro Koskinen1-243/+270
Use __BITFIELD_FIELD to define bitfields. OCTEON can at least in theory run also in little-endian mode, so the bitfield definitions should not assume big-endian byte order. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-24staging: octeon-usb: delete redundant field from octeon_temp_bufferAaro Koskinen1-4/+1

2015-03-24staging: octeon-usb: remove useless prefix from internal routinesAaro Koskinen1-219/+205
Original CVMX code used "__" to distinguis internal USB functions from public ones. But in Linux all cvmx_usb routines are internal to this driver, so such separation is useless. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-24staging: octeon-usb: eliminate 64-bit register access wrappersAaro Koskinen1-75/+33

2014-12-15Merge tag 'staging-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/stagingLinus Torvalds1-28/+41
Pull staging driver updates from Greg KH: "Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.
