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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
