I'm use i.MX6Dual proc with kernel 4.13.0. I have external device, that I control via SPI interface. I have spidev0.0 and it's work well. But I want change inactive state of data line to low. Default inactive state is high. At reference manual I was find register ECSPIx_CONFIGREG that contain DATA_CTL field, that control inactive state of data line. I try update this field in spi driver init, but it's don't work. I don't understud, at what step in kernel I must edit this field.

Can anybody help me in this question? Thank you!
