Rely on the reset/bootloader values isn't that good at all. Since the bootloader use case can be different. I've checked your patch against a vanilla barebox (bootloader) which includes this devicetree. My test setup was a imx6q pfla02 SoM and a pbab01 baseboard.

So I'm fine with the patch.

So I'm fine with the patch. This is a bug in my linter's data table. EIM_EB3 should use 0x1b0b0 on both imx6q and imx6dl. I will wait a bit more for feedback, and then probably respin with this fixed. Thanks for your input. Best regards Uwe

Instead of relying on reset defaults or a bootloader to configure use explicit values for the swpad configuration. Here the reset defaults of the i.MX6dl are used owing to lack of other evidence. (They differ from the i.MX6q defaults for GPIO_0 and KEY_ROW4.)
