Hello everyone,
I am using the STM32MP135 SoM from PHYTEC, and I’m creating a custom device tree source (DTS) file tailored to our carrier board. I’m having trouble controlling the backlight PWM signal. I’m unable to enable the PWM and enable signal as expected, although I can change the enable pin status if I remove the enable pin definition from the backlight node. Additionally, there is no [used] indication next to GPIOI pin 0, which I’ve configured as the panel enable GPIO. I suspect this issue may be related to the LCD node configuration.
I’ve attached my GPIO states and the DTS file for reference.
