[fulinux]

Dear Communty,

our board is imx6q,i am porting linux-4.1.15, i need to run a 1920*1080 lvds screen, this screen need large power(backlight Vmin = 60v), so we add a power supply circuit for screen. there are schematics of lcd power as follows:

1、

2、

3、

4、

5、

As you can see，we should add three gpios to control power sequence, there are 'lcd_power_on', 'lcd_en' and 'backlight_power_on'. how should i configure device tree, or add and modify codes. it had troubled me for a long time.

anyone can help me?

Looking forward to your reply！

Best regards

Hi fulinux

in linux one can add init codes to board file  mach-imx6q.c

linux-2.6-imx.git - Freescale i.MX Linux Tree

in uboot  this may be ../mx6sabresd/mx6sabresd.c

also please refer to attached Porting Guide

Best regards

igor
