[ Upstream commit66d9506440] So far, we walked the orphan list every time a new clock was registered in CCF. This was fine since the clocks were only referenced by name. Now that the clock can be referenced through DT, it is not enough: * Controller A register first a reference clocks from controller B through DT. * Controller B register all its clocks then register the provider. Each time controller B registers a new clock, the orphan list is walked but it can't match since the provider is registered yet. When the provider is finally registered, the orphan list is not walked unless another clock is registered afterward. This can lead to situation where some clocks remain orphaned even if the parent is available. Walking the orphan list on provider registration solves the problem.

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.
