It also replaces two usages of max_packet which were clearly intended to be max_burst all along. More importantly, it compensates for a common bug in high-speed bulk endpoint descriptors. In many devices there is a bulk endpoint having a wMaxPacketSize value smaller than 512, which is forbidden by the USB spec. Some xHCI controllers can't handle this and refuse to accept the endpoint. This patch changes the max_packet value to 512, which allows the controller to use the endpoint properly. In practice the bogus maxpacket size doesn't matter, because none of the transfers sent via these endpoints are longer than the maxpacket value anyway.

This patch fixes the problem by rearranging the dependencies. Now the platform-dependent config options don't depend on USB_UHCI_HCD; instead it depends on them. Furthermore, there is no user-selectable choice as to which glue modules will be built. If USB_UHCI_HCD is enabled then all applicable bus glues will be built.

This provokes a warning message from uhci-hcd in the auto-stop case. To prevent this from happening, this patch adds a test to avoid performing an auto-stop when the wait_for_hp quirk flag is set. The controller will still suspend through the normal runtime PM mechanism. And since that pathway includes a 1-ms delay, the slowness of the virtual hardware won't matter.

I suspect this code originated in commit 4a53f4e "USB: ehci-tegra: add probing through device tree" and was simply copied everywhere else. This works fine when the code is built-in, but can cause a crash when the code is in a module. The first module load sets up the dma_mask pointer, but if the module is removed and re-inserted, the value is now non-NULL, and hence is not updated to point at the new location, and hence points at a stale location within the previous module load address, which in turn causes a crash if the pointer is de-referenced. The simplest way of solving this seems to be to copy the code from ehci-platform.c, which uses the coherent_dma_mask as the target for the dma_mask pointer.
