The current interconnect rpm driver uses a single aggregate bandwidth to calculate the clock rates for both active and sleep clocks; therefore, it has no chance to separate bandwidth requests for these two kinds of clocks. This patch studies the implementation from interconnect rpmh driver to support multiple buckets. The rpmh driver provides three buckets for AMC, WAKE, and SLEEP; this driver only needs to use WAKE and SLEEP buckets, but we keep the same way with rpmh driver, this can allow us to reuse the DT binding and avoid to define duplicated data structures. This patch introduces two callbacks: qcom_icc_pre_bw_aggregate() is used to clean up bucket values before aggregate bandwidth requests, and qcom_icc_bw_aggregate() is to aggregate bandwidth for buckets.

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.
