When dma is disabled inside dwc2 (because the hardware does not support it, or the code was changed to disable it for testing), let the usb core know about this by clearing hcd->self.uses_dma. By default, the usb core assumes that dma is used when a dma_mask is set, but this might not always match the dma_enable value in dwc2. To prevent problems resulting from a mismatch, better to explicitely disable dma in this case (though everything seemed to work with the wrong value of uses_dma as well, probably only resulted in some unneeded work).

If the platform or bus driver failed to setup a dma_mask, but the hardware advertises support for DMA, before DMA would be enabled in dwc2, but disabled in the usb core, making all connectivity break. With this commit, the dwc2 driver will emit a warning and fall back to slave mode in this case. Note that since commit 642f2ecc (staging: dwc2: Fix dma-enabled platform devices using a default dma_mask) the platform bindings make sure a DMA mask is always present, but having this check here anyway is probably a good from a defensive programming standpoint (in case of changes to platform.c or addition of new glue layers).

The dwc2 driver sets the value of the DWC2 GAHBCFG register to 0x6, which is GAHBCFG_HBSTLEN_INCR4. But different platforms may require different values. In particular, the Broadcom 2835 SOC used in the Raspberry Pi needs a value of 0x10, otherwise the DWC2 controller stops working after a short period of heavy USB traffic. So this patch adds another driver parameter named 'ahbcfg'. The default value is 0x6. Any platform needing a different value should add a DT attribute to set it. This patch also removes the 'ahb_single' driver parameter, since that bit can now be set using 'ahbcfg'. This patch does not add DT support to platform.c, I will leave that to whoever owns the first platform that needs a non-default value. (Stephen?) Signed-off-by:

Remove the use of bus_to_virt() and just fail the transfer if an unaligned buffer with no virtual address is found. AFAIK that can't happen anyway. Also change setting of coherent DMA mask to the normal 32 bits. 31 bits was only needed when calling bus_to_virt() AFAICR. Signed-off-by:

The parameters to dwc2_host_complete() didn't make much sense. The 'context' parameter always came from the ->priv member of the 'dwc2_urb' parameter, and both of those always came from a struct dwc2_qtd. So just pass in the struct dwc2_qtd instead. This also allows us to null out the dwc2_qtd->urb member after it is freed, which the calling code forgot to do in several places, causing random driver crashes from dereferencing the freed pointer. This also requires the calls to dwc2_hc_handle_tt_clear() to be moved before the calls to dwc2_host_complete(), otherwise that routine would do nothing because dwc2_qtd->urb has already been freed.
