Hi Christian

flexio timings are described insect.27.4.4.2 Pin Synchronization,

sect.27.5 Application Information, sect.27.5.3 SPI Master i.MX RT1050

Processor Reference Manual :
maximum baud rate is divide by 4 of the FlexIO clock frequency.

https://www.nxp.com/docs/en/reference-manual/IMXRT1050RM.pdf

Max. frequency can be found in Table 18-4. System Clock Frequency Values

Best regards
igor
