Kernel sources for Moto G9 (Play) (Guamp)

HiKey960 doesn't play well with the inline crypto logic, and seems to deviate from the UFS standard. Eric Biggers noted: "It declares that it has 32 crypto configurations (a.k.a. keyslots), starting at offset 1280 from the start of the UFS registers. Per the UFS standard, each crypto configuration is 128 bytes, so that means they go until offset 5376. However, the device tree node for the UFS host controller (in hi3660.dtsi) only declares 4096 bytes for the UFS standard registers, and then the next 4096 physical bytes are declared to be vendor-specific UFS registers. The ufs-hisi driver already uses these vendor-specific registers to do things like reset the UFS controller and configure the clocks. But if we follow the UFS standard, the very same memory addresses have a different meaning. Also, even if I hardcode the number of keyslots to 22 so they fit in the first 4096 bytes, then there is either an SError interrupt while programming keyslot 0, or CRYPTO_GENERAL_ERROR is reported from the UFS request." So until we can understand the hardware better disable inline crypto using the quirks flag in the driver.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
