[PATCH v3 1/2] usb: dwc2: alloc dma aligned buffer for isoc split in

The commit 3bc04e28a030 ("usb: dwc2: host: Get aligned DMA in a more supported way") rips out a lot of code to simply the allocation of aligned DMA. However, it also introduces a new issue when use isoc split in transfer. In my test case, I connect the dwc2 controller with an usb hs Hub

[PATCH v3 2/2] usb: dwc2: fix isoc split in transfer with no data

If isoc split in transfer with no data (the length of DATA0 packet is zero), we can't simply return immediately. Because the DATA0 can be the first transaction or the second transaction for the isoc split in transaction. If the DATA0 packet with no data is in the first transaction, we can return

Non-BCD bcdDevice values

Some devices have a non-BCD value in bcdDevice. For example some card readers based on an ICSI chip have bcdDevice 0x016F. (They put "1.6F" in bytes 32-35 of their INQUIRY data.) For devices which need US_FL_FIX_INQUIRY, fill_inquiry_response() doesn't appear to handle non-BCD values correctly
