SION works! I did not know about it :). I see the imxrt1020-evk, imxrt1050-evk and imx53-kp use it in their device tree. To make this feature available, I had to ensure the IMX_PAD_SION was available in my dts by adding a define: #define IMX_PAD_SION 0x40000000 I could then configure the pinmux in my dts file. It would be nice to make this define available by default. To conclude, I would now need to enable SION in order to remove the 'Warning: value of pin is still 0' text in my serial output. I'm fine with that.
