Abel Vesa 480374c75c arm64: dts: qcom: x1e80100: Fix USB combo PHYs SS1 and SS2 ref clocks 
[ Upstream commit 3af51501e2 ]

It seems the USB combo SS1 and SS2 ref clocks have another gate, unlike
the SS0. These gates are part of the TCSR clock controller.

At least on Dell XPS 13 (9345), if the ref clock provided by the TCSR
clock controller for SS1 PHY is disabled on the clk_disable_unused late
initcall, the PHY fails to initialize. It doesn't happen on the SS0 PHY
and the SS2 is not used on this device.

This doesn't seem to be a problem on CRD though. It might be that the
RPMh has a vote for it from some other consumer and does not actually
disable it when ther kernel drops its vote.

Either way, these TCSR provided clocks seem to be the correct ones for
the SS1 and SS2, so use them instead.

README 

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.
