commit 72ceafb587a56e26c905472418c7dc2033c294d3 upstream. The crypto_ahb and crypto_axi clks are hardware voteable. This means that the halt bit isn't reliable because some other voter in the system, e.g. TrustZone, could be keeping the clk enabled when the kernel turns it off from clk_disable(). Make these clks use voting mode by changing the halt check to BRANCH_HALT_VOTED and toggle the voting bit in the voting register instead of directly controlling the branch by writing to the branch register. This fixes stuck clk warnings seen on ipq9574 and saves power by actually turning the clk off. Also changes the CRYPTO_AHB_CLK_ENA & CRYPTO_AXI_CLK_ENA offset to 0xb004 from 0x16014.

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.
