The RZ/V2H(P) (R9A09G057) SoC is equipped with the Generic Timer Module, also known as OSTM. Similar to the RZ/G2L SoC, the OSTM on the RZ/V2H(P) SoC requires the reset line to be deasserted before accessing any registers. Early call to ostm_init() happens through TIMER_OF_DECLARE() which always fails with -EPROBE_DEFER, as resets are not available that early in the boot process. To address this issue on the RZ/V2H(P) SoC, enable the OSTM driver to be reprobed through the platform driver probe mechanism.

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 reStructuredText 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.
