Linux kernel source tree
065d5885f6
At probe time the driver would display the following error and abort: xilinx-psgtr fd400000.phy: Invalid rate 0 for reference clock 0 At probe time, the associated GTR driver (e.g. SATA or PCIe) hasn't initialized the clock yet, so clk_get_rate() likely returns 0 if the clock is programmable. So this driver only works if the clock is fixed. The PHY driver doesn't need to know the clock frequency at probe yet, so wait until the associated driver initializes the lane before requesting the clock rate setting. In addition to allowing the driver to be used with programmable clocks, this also reduces the driver's runtime memory footprint by removing an array of pointers from struct xpsgtr_phy.

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 reStructuredText 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.
