- *
- * struct foo_driver_platform_data {

- * Note that the generic "device_enable" name is used, rather than

- *
- * This should be populated during device setup:
- *
- * ...
- * pdata->device_enable = omap_device_enable;

- *
- * 2. Drivers should first check to ensure the function pointer is not null
- * before calling it, as in:
- *
- * if (pdata->device_enable)
- * pdata->device_enable(pdev);
- *
- * This allows other architectures that don't use similar device_enable()/
- * device_shutdown() functions to execute normally.
- *
- * ...
- *
- * Suggested usage by device drivers:
- *
- * During device initialization:
- * device_enable()
- *
- * During device idle:
- * (save remaining device context if necessary)
- * device_idle();
- *
- * During device resume:
- * device_enable();
- * (restore context if necessary)
- *
- * During device shutdown:
- * device_shutdown()
- * (device must be reinitialized at this point to use it again)
