Currently NOC_QOS_MODE_FIXED is defined as 0x0 which makes it the default option (partial struct initialization). The default option however should be NOC_QOS_MODE_INVALID. That results in bogus QoS configurations being sent for port 0 (which is used for the DRAM endpoint on BIMC, for example) coming from all nodes with .qos.ap_owned = true and uninitialized .qos.qos_mode. It's also an issue for newer SoCs where all nodes are treated as if they were ap_owned, but not all of them have QoS configuration. The NOC_QOS_MODEs are defined as preprocessor constants and are not used anywhere outside qcom_icc_set_noc_qos(), which is easily worked around. Separate the desc->type values from the values sent to msmbus in the aforementioned function. Make the former an enum for better mainainability.

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.
