The GCC_UFS_REF_CLKREF_CLK must be enabled or the second UFS controller
fails to enumerate on sa8295p-adp.
Note that the vendor kernel enables both GCC_UFS_REF_CLKREF_CLK and
GCC_UFS_1_CARD_CLKREF_CLK and it is possible that the former should be
modelled as a parent of the latter. The clock driver also has a
GCC_UFS_CARD_CLKREF_CLK clock which the firmware appears to enable on
the ADP.
The usual lack of documentation for Qualcomm SoCs makes this a highly
annoying guessing game, but as the second controller works on the ADP
without either card reference clock enabled, only enable
GCC_UFS_REF_CLKREF_CLK for now.

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.
