LCD Reset pin management on iMX7

Hello,

In order to drive a LCD screen connected to an iMX7 I need to drive the Reset (Bit 0) of LCDIFx_CTRL1n register. I would like to know if this pin is automatically managed by the Linux LCD management stack or I need to control it manually.

If Linux driver manages this pin automatically, in which case the LCD would be reset?

Thanks in advance for your help.

sect.6.3.4.4 Source Code Structure attached Linux manual and

linux sources on

linux-imx - i.MX Linux kernel
