Full understand, I checked, same. We can forgot about this because I need to have hardware RS485 but big thanks that you tried to help
Do you know why I am able to manage GPIO to work with the AMBA driver in Linux 5.10, but it seems to be a problem in version 6.6? In 5.10, I was able to add code below to function pl011_probe
but now return

Code:
ret = devm_gpio_request(&dev->dev, MOO_GPIO_NO, "pl011-serial");if (ret < 0) {pr_err("gpio_req says nay\n");return ret;}ret = gpio_direction_output(MOO_GPIO_NO, 1);if (ret < 0) {pr_err("gpio_dir says nay\n");return ret;}Code:
