+ according to silicon characteristics and operating
+ conditions. Enabling SmartReflex reduces power
+ consumption.
+
+ Please note, that by default SmartReflex is only
+ initialized. To enable the automatic voltage

+ user must write 1 to
+ /debug/voltage/vdd_<X>/smartreflex/autocomp,

+ Optionally autocompensation can be enabled in the kernel
+ by default during system init via the enable_on_init flag

+ * @dev: struct device *
+ *
+ * This function returns the number of times that the device @dev has
+ * lost its internal context. This generally occurs on a powerdomain
+ * transition to OFF. Drivers use this as an optimization to avoid restoring
+ * context if the device hasn't lost it. To use, drivers should initially
+ * call this in their context save functions and store the result. Early in
+ * the driver's context restore function, the driver should call this function
+ * again, and compare the result to the stored counter. If they differ, the
+ * driver must restore device context. If the number of context losses
+ * exceeds the maximum positive integer, the function will wrap to 0 and
+ * continue counting. Returns the number of context losses for this device,
+ * or negative value upon error.

+ * This code provides a consistent interface for OMAP device drivers
+ * to control power management and interconnect properties of their
+ * devices.
+ *
+ * In the medium- to long-term, this code should either be
+ * a) implemented via arch-specific pointers in platform_data
+ * or
+ * b) implemented as a proper omap_bus/omap_device in Linux, no more
+ * platform_data func pointers
+ *
+ *
+ * Guidelines for usage by driver authors:
+ *
+ * 1. These functions are intended to be used by device drivers via
+ * function pointers in struct platform_data. As an example,
+ * omap_device_enable() should be passed to the driver as
+ *
+ * struct foo_driver_platform_data {
+ * ...
+ * int (*device_enable)(struct platform_device *pdev);
+ * ...
+ * }
+ *
+ * Note that the generic "device_enable" name is used, rather than
+ * "omap_device_enable". This is so other architectures can pass in their
+ * own enable/disable functions here.
+ *
+ * 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)
