Raviteja Laggyshetty c95e4c4caf interconnect: qcom: sdx75: Drop QPIC interconnect and BCM nodes
commit 295f58fdcc upstream.

As like other SDX SoCs, SDX75 SoC's QPIC BCM resource was modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect and BCM node mistakenly. It is incorrect to
describe the same resource in two different providers, as it will lead to
votes from clients overriding each other.

Hence, drop the QPIC interconnect and BCM nodes and let the clients use
clk-rpmh driver to vote for this resource.

Without this change, the NAND driver fails to probe on SDX75, as the
interconnect sync state disables the QPIC nodes as there were no clients
voting for this ICC resource. However, the NAND driver had already voted
for this BCM resource through the clk-rpmh driver. Since both votes come
from Linux, RPMh was unable to distinguish between these two and ends up
disabling the QPIC resource during sync state.

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.
