QMP PHY for USB/PCIE requires pipe_clk for locking of retime buffers at the pipe interface. Driver checks for PHY_STATUS without enabling pipe_clk due to which phy_init() fails with initialization timeout. Though pipe_clk is output from PHY (after PLL is programmed during initialization sequence) to GCC clock_ctl and then fed back to PHY but for PHY_STATUS register to reflect successful initialization pipe_clk from GCC must be present. Since, clock driver now ignores status_check for pipe_clk on clk_enable/disable, driver can safely enable/disable pipe_clk from phy_init/exit.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
