In this case we can't tell if you are going to use these headers later or not. Hence review is more complex. I'll have a brief go at reviewing, but reality is a real review needs to be easier to do than it is here! I will note though that alphabetical order, perhaps with iio includes in their own block is preferred for headers in IIO drivers. > + > +#define ADC_DRIVER_NAME "imx8qxp-adc" > + > +static int imx8qxp_adc_probe(struct platform_device *pdev) > +{ > + return 0; > +} > + > +static int imx8qxp_adc_remove(struct platform_device *pdev) > +{ > + return 0; > +} > + > +static int imx8qxp_adc_runtime_suspend(struct device *dev) > +{ > + return 0; > +} > + > +static int imx8qxp_adc_runtime_resume(struct device *dev) > +{ > + return 0; > +} > + > +static const struct dev_pm_ops imx8qxp_adc_pm_ops = { > + SET_SYSTEM_SLEEP_PM_OPS(pm_runtime_force_suspend, pm_runtime_force_resume) > + SET_RUNTIME_PM_OPS(imx8qxp_adc_runtime_suspend, imx8qxp_adc_runtime_resume, NULL) > +}; > + > +static const struct of_device_id imx8qxp_adc_match[] = { > + { .compatible = "nxp,imx8qxp-adc", }, > + { /* sentinel */ } > +}; > +MODULE_DEVICE_TABLE(of, imx8qxp_adc_match); > + > +static struct platform_driver imx8qxp_adc_driver = { > + .probe = imx8qxp_adc_probe, > + .remove = imx8qxp_adc_remove, > + .driver = { > + .name = ADC_DRIVER_NAME, > + .of_match_table = imx8qxp_adc_match, > + .pm = &imx8qxp_adc_pm_ops, > + }, > +}; > + > +module_platform_driver(imx8qxp_adc_driver); > + > +MODULE_DESCRIPTION("i.MX8QuadXPlus ADC driver"); > +MODULE_LICENSE("GPL v2");
