How can I control the spi clk

We are using a custom imx6dl board which I am attempting to use for communications with a BLE module. This module requires that two clk cycles be detected before and after each SPI transaction, like so:


I would like to modify the spi-imx driver to support this behavior, but it is not clear to me how the clock is controlled. Enabling or disabling the clock does not seem to trigger the cycles. I would like some guidance on how I can proceed from here.
