2010-05-17DMA ENGINE: Do not reset 'private' of channelJassi Brar1-2/+0
The member 'private' of 'struct dma_chan' is meant for passing data between client and the controller driver. The DMA client driver may point it to platform specific stuff after acquiring the channel. So, it is the responsiblity of the same code to reset it, if it must. The DMA engine doesn't set it and hence, shouldn't reset it either. This reseting of private by DMA Engine comes in the way of implementing default channel settings during DMAC probe. That capability is useful for not having the clients to always provide platform specific data, like Rx/Tx FIFO addresses, which usually doesn't change across channel requests.

2010-03-19USB: xhci: Make endpoint interval debugging clearer.Sarah Sharp1-2/+7

2010-03-19USB: Fix usb_fill_int_urb for SuperSpeed devicesMatthew Wilcox2-5/+14
USB 3 and Wireless USB specify a logarithmic encoding of the endpoint interval that matches the USB 2 specification. usb_fill_int_urb() didn't know that and was filling in the interval as if it was USB 1.1. Fix usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case alone, because David Vrabel wants to keep the old encoding. Update the struct urb kernel doc to note that SuperSpeed URBs must have urb->interval specified in microframes. Add a missing break statement in the usb_submit_urb() interrupt URB checking, since wireless USB and SuperSpeed USB encode urb->interval differently. This allows xHCI roothubs to actually register with khubd.
