This adds support for OHCI on AT91rm9200 based boards. Possibly of interest here is the way this uses <linux/clk.h> to gate clocks on/off during system pm state transitions. That's typical for non-PCI systems. Some can go further; Mini-A host side connectors enable ID-pin sensing. From: Andrew Victor <andrew@sanpeople.com> Signed-off-by:

This patch modifies the behavior of the EHCI driver in an unlink path that seems to be causing various issues on some systems. Those problems have included issues with disconnection, driver unbinding, and similar cases where urb unlinking would just not work right. This patch should help avoid those problems by not turning off the async (control/bulk) schedule until it's not expecting an "async advance" IRQ, which comes from the processing passing the schedule head. Whether the driver attempts to do such things is dependent on system timings, so many folk would never have seen these problems. Signed-off-by:

On the MPC834x processors the multiport host (MPH) EHCI controller has an erratum in which the port number in the queue head expects to be 0..N-1 instead of 1..N. If we are on one of these chips we subtract one from the port number before putting it into the queue head. Signed-off-by:

Adding a Host Mode USB driver for the Freescale 83xx. This driver supports both the Dual-Role (DR) controller and the Multi-Port-Host (MPH) controller present in the Freescale MPC8349. It has been tested with the MPC8349CDS reference system. This driver depends on platform support code for setting up the pins on the device package in a manner appropriate for the board in use. Note that this patch requires selecting the EHCI controller option under the USB Host menu. Signed-off-by:

This patch replaces the split ISO raw_mask calculation code in the iso_stream_init() function that computed incorrect numbers of high speed transactions for both input and output transfers. In the output case, it added a superfluous start-split transaction for all maxmimum packet sizes that are a multiple of 188. In the input case, it forgot to add complete-split transactions for all microframes covered by the full speed transaction, and the additional complete-split transaction needed for the case when full speed data starts arriving near the end of a microframe. These changes don't affect the lack of full speed bandwidth, but at least it removes the MMF errors that the HC raised with some input streams. Signed-off-by:

This teaches the EHCI driver about a quirk seen in older NForce2 chips, adding a workaround to ignore selective suspend requests. Bus-wide (so-called "global") suspend still works, as does USB wakeup of a root hub that's globally suspended. There's still a hole in this support though. Strictly speaking, this should _fail_ selective suspend requests, rather than ignoring them, since doing it this way means that devices which should be able to issue remote wakeup are not going to be able to do that. For now, we'll just live with that problem ... since usbcore expects to do selective suspend on the way towards a full bus suspend, and usbcore needs to be able to do full bus suspend. Signed-off-by:

We only need to write an invalid tag every 16 bytes, so taking advantage of this can save many instructions compared to the simple memset() call we make now. A prefetching implementation is implemented for sun4u and a block-init store version if implemented for Niagara. The next trick is to be able to perform an init and a copy_tsb() in parallel when growing a TSB table. Signed-off-by: -
