Partially reverts commit128f825aea("ASoC: max98357a: move control of SD_MODE to DAPM"). In order to have mute control of max98357 from machine drivers, commit128f825aea("ASoC: max98357a: move control of SD_MODE to DAPM") moves the control of SD_MODE from DAI ops to DAPM events. However, pop noise has been observed on rk3399-gru-kevin boards due to this commit. The commit128f825aeacaused sequence of DAI clocks and SD_MODE changed on rk3399-gru-kevin boards. With the commit128f825aea: - SD_MODE will be set to 1 before DAI clocks start. - SD_MODE will be set to 0 after DAI clocks stop. As a result, pop noise. Moves the control of SD_MODE back to DAI ops. In the meantime, uses an additional flag in DAPM event to provide chance of mute control for machine drivers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
