Hi Saravana, Thus wrote Saravana Kannan (saravanak@xxxxxxxxxx): > Martin, > If you tested this series, can you please give a Tested-by? I tested this v2 series on top of next-20210202 (without the fsl,avic patch). If modules are enabled, the kernel doesn't boot on my imx25 board. This is expected, I guess. With modules disabled, the kernel boots but probe fails for some (non-mainline) drivers in my tree. All of those drivers have a gpio in their device-tree node, such as my_driver { gpio_test1 = <&gpio1 0 0>; ... }; with gpio1 from arch/arm/boot/dts/imx25.dtsi. The probe function calls of_get_named_gpio(np, "gpio_test1", 0); to get the gpio. This fails with -EINVAL. Best regards, Martin
