There are unused clocks that need to remain untouched by clk_disable_unused, and most likely could be disabled later on sync_state. So provide a generic sync_state callback for the clock providers that register such clocks. Then, use the same mechanism as clk_disable_unused from that generic callback, but pass the device to make sure only the clocks belonging to the current clock provider get disabled, if unused. Also, during the default clk_disable_unused, if the driver that registered the clock has the generic clk_sync_state_disable_unused callback set for sync_state, skip disabling its clocks.

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.
