A high speed hub has a special responsibility to handle full speed/ low speed devices connected on downstream ports. In this case, the hub must isolate the high speed signaling environment from the full speed/low speed signaling environment with the help of Transaction Translator (TT). TT details are provided by hub descriptors and we parse and save it to hub uclass_priv for later use. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
