iMX8QXP-LED Configuration in device tree

kinjalGediya — Thu, 01 Oct 2020 07:22:48 GMT

Hello NXP,

I am using custom board of iMX8QXP. RGB LEDs are present in custom board and I want to access LED as GPIO.

we have added node for gpio in device tree but we are not able to on-off LEDS.

RGB LEDs are connected with GPIO1_IO27,GPIO1_IO28,GPIO1_IO30

Can you guide me how to configure LEDs as a GPIO in device tree?
