ARCH_MXC does not depend on OF yet, but I agree this is a good suggestion and will submit a patch to do so. For the time being, I will keep the OF dependency in the driver. > If we truly converting this driver then we should also remove references > to dev_get_platdata() and checks for pdev->dev.of_node from > imx_keypad_probe. Good point. I removed them in v2. Thanks

i.MX has been converted to a DT-only platform, so make the driver depend on OF, remove the CONFIG_OF ifdefery and remove of_match_ptr().
