Hi Adam,

What about the following lines in run_descriptor_deco0()? Does this 
condition also apply to i.MX8MM?

drivers/crypto/caam/ctrl.c:

	if (ctrlpriv->virt_en == 1 ||
	    /*
	     * Apparently on i.MX8MQ it doesn't matter if virt_en == 1
	     * and the following steps should be performed regardless
	     */
	    of_machine_is_compatible("fsl,imx8mq")) {
		clrsetbits_32(&ctrl->deco_rsr, 0, DECORSR_JR0);

		while (!(rd_reg32(&ctrl->deco_rsr) & DECORSR_VALID) &&
		       --timeout)
			cpu_relax();

		timeout = 100000;
	}

Regards,
Frieder
