The spi-ti-qspi driver initializes its spi clock by the spi-max-frequency property from the controller node, and ignores per-transfer (and per-slave) speed_hz settings. Isolate clock settings out from ti_qspi_setup() and call it from ti_qspi_start_transfer_one() and ti_qspi_exec_mem_op(), using per-transfer speed_hz and per-slave max_speed_hz settings. Also drop spi_max_frequency from struct ti_qspi and use spi_master's max_speed_hz.

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.
