usb: xhci: fix lack of short packet event trb handling

2020-12-16T09:27:09Z

For bulk IN transfer, the codes will set ISP flag to request event TRB being generated by xHC for the case of short packet. So when encountering buffer-cross-64K-boundary (which we will divide payload and enqueuqe more than 1 transfer TRB), and the first TRB ends up with a short packet condition it will trigger an short packet code transfer event per that flag and cause more than 1 event TRB generated for this transfer. However, current codes will only handle the first transfer event TRB then mark current transfer completed, causing next transfer failure due to event TRB mis-match. Such issue has been observed on some Layerscape platforms (LS1028A, LS1088A, etc) with USB ethernet device. This patch adds a loop to make sure the event TRB for last transfer TRB has been handled in time. Signed-off-by: Ran Wang Reviewed-by: Bin Meng

usb: xhci: xhci_bulk_tx: Don't "BUG" when comparing addresses

2020-10-07T18:25:57Z

Octeon uses mapped addresses for virtual and physical memory. It's not that easy to calculate the resulting addresses here. So let's remove this BUG_ON() completely, as it's not really helpful. Please also note, that BUG_ON() is not recommended any more in the Linux kernel. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

On MIPS platforms, mapping of the base address is needed. This patch switches from dev_get_addr() to dev_remap_addr() to get the mapped base address of the xHCI controller. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

dm: add cells_count parameter in *_count_phandle_with_args

2020-10-06T15:07:54Z

The cell_count argument is required when cells_name is NULL. This patch adds this parameter in live tree API - of_count_phandle_with_args - ofnode_count_phandle_with_args - dev_count_phandle_with_args This parameter solves issue when these API is used to count the number of element of a cell without cell name. This parameter allow to force the size cell. For example: count = dev_count_phandle_with_args(dev, "array", NULL, 3); Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass
