The remoteproc driver is split between the responsibilities of getting the SoC-internal ARM core up and running and the external RF (aka "Iris") part configured. In order to satisfy the regulator framework's need of a struct device * to look up supplies this was implemented as two different drivers, using of_platform_populate() in the remoteproc part to probe the iris part. Unfortunately it's possible that the iris part probe defers on yet not available regulators and an attempt to start the remoteproc will have to be rejected, until this has been resolved. But there's no useful mechanism of knowing when this would be. Instead replace the of_platform_populate() and the iris probe with a function that rolls its own struct device, with the relevant of_node associated that is enough to acquire regulators and clocks specified in the DT node and that may propagate the EPROBE_DEFER back to the wcnss device's probe.

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.
