[ Upstream commitc2b6cdee1d] After system entered Suspend to RAM, registers setting of this hardware is reset because the SoC will be turned off. On R-Car Gen3 (info->ccc_gac), ravb_ptp_init() is called in ravb_probe() only. So, after system resumed, it lacks of the initial settings for ptp. So, add ravb_ptp_{init,stop}() into ravb_{resume,suspend}().

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.
