I used the board customized by imx8mq and developed the code from imx8mq_evk.Encountered a problem: reboot when the i2c SDA pulled down after failed to restore the i2c lethal lock.

I observed the board of imx8mq_evk, and there was no reset pin of PTN5110.So how does it avoid this problem?Did you control the power?

thank you so mach~~ Reset i2c waveform
