-Subject: [PATCH 190/224] usb: xhci-mtk: supports remote wakeup for mt2712 with
- two xHCI IPs
-
-The old way of usb wakeup only supports platform with single xHCI IP,
-such as mt8173, but mt2712 has two xHCI IPs, so rebuild its flow and
-supports the new glue layer of usb wakeup on mt2712 which is different
-from mt8173.
-Due to there is a hardware bug with the LINE STATE wakeup mode on
-mt8173 which causes wakeup failure by low speed devices, and also
-because IP SLEEP mode can cover all functions of LINE STATE mode,
-it is unused in fact, and will not support it later, so remove it at
-the same time.
