Georgi Djakov 5be1805dc3 interconnect: qcom: sdm845: Enable keepalive for the MM1 BCM
After enabling interconnect scaling for display on the db845c board,
in certain configurations the board hangs, while the following errors
are observed on the console:

  Error sending AMC RPMH requests (-110)
  qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
  qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
  qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
  ...

In this specific case, the above is related to one of the sequencers
being stuck, while client drivers are returning from probe and trying
to disable the currently unused clock and interconnect resources.
Generally we want to keep the multimedia NoC enabled like the rest of
the NoCs, so let's set the keepalive flag on it too.

Fixes: aae57773fb ("interconnect: qcom: sdm845: Split qnodes into their respective NoCs")

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 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.
