[ Upstream commitba1d366de2] When MSM8998 support was added, and analysis was done to determine what clocks would be consumed. That analysis had a flaw, which caused the pnoc to be skipped. The pnoc clock needs to be on to access the uart for the console. The clock is on from boot, but has no consumer votes in the RPM. When we attempt to boot the modem, it causes the RPM to turn off pnoc, which kills our access to the console and causes CPU hangs. We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in an implicit vote for linux and prevent issues when booting modem. Hopefully pnoc can be consumed by the interconnect framework in future so that Linux can rely on explicit votes.

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.
