[ Upstream commit af98caeaa7b6ad11eb7b7c8bfaddc769df2889f3 ] This register is important for sequencing the commands to PLLs, so actually write the update bits with regmap_write_bits() instead of relying on a read/modify/write regmap command that could skip the actual hardware write if the value is identical to the one read. It's changed when modification is needed to the PLL, when read-only operation is done, we could keep the call to regmap_update_bits(). Add a comment to the sam9x60_div_pll_set_div() function that uses this PLL_UPDT register so that it's used consistently, according to the product's datasheet.

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.
