imx8mp ecspi miso runtime correction

we are using ecspi2 on ima8mp to connect extern ADC. if running spi on rather high speeds (20MHz) we have a runtime between SCLK and MISO of ~3 bits caused by ADUM1401 for galvanic insulation. i know from renesas rz/t1 we use in other system that there is a configurable runtime correction for MISO compared to SCLK that is great for handling such issues.

I searched the imx8mp manual but did not find something like this. is there a possibility to have that on imx8mp, of playing arround with polarity and phase does not help anymore?

Hi @martmanmtx!
Thank you for contacting NXP Support!

By hardware, our IP doesn't have that feature but you can refer to our Linux Reference Manual, maybe you can implement the feature on software modifying our driver.

Sorry for the mistake!

Best Regards!
