commit6c8bf4b604upstream. The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK twice instead of checking both SOFT_RESET_MSK (bit 0) and SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check. The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via regmap_update_bits(), then polls for them to be cleared. Since we set both bits before polling, we should be waiting for both to clear. Fix by using both masks as done in regmap_update_bits() above.

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.
