15 | * | ||
16 | * This code provides a consistent interface for OMAP device drivers | ||
17 | * to control power management and interconnect properties of their | ||
18 | * devices. | ||
19 | * | ||
20 | * In the medium- to long-term, this code should either be | ||
21 | * a) implemented via arch-specific pointers in platform_data | ||
22 | * or | ||
23 | * b) implemented as a proper omap_bus/omap_device in Linux, no more | ||
24 | * platform_data func pointers | ||
25 | * | ||
26 | * | ||
27 | * Guidelines for usage by driver authors: | ||
28 | * | ||
29 | * 1. These functions are intended to be used by device drivers via | ||
30 | * function pointers in struct platform_data. As an example, | ||
31 | * omap_device_enable() should be passed to the driver as | ||
32 | * | ||
33 | * struct foo_driver_platform_data { | ||
34 | * ... | ||
35 | * int (*device_enable)(struct platform_device *pdev); | ||
36 | * ... | ||
37 | * } | ||
38 | * | ||
39 | * Note that the generic "device_enable" name is used, rather than | ||
40 | * "omap_device_enable". This is so other architectures can pass in their | ||
41 | * own enable/disable functions here. | ||
42 | * | ||
43 | * This should be populated during device setup: | ||
44 | * | ||
45 | * ... | ||
46 | * pdata->device_enable = omap_device_enable; | ||
47 | * ... | ||
48 | * | ||
49 | * 2. Drivers should first check to ensure the function pointer is not null | ||
50 | * before calling it, as in: | ||
51 | * | ||
52 | * if (pdata->device_enable) | ||
53 | * pdata->device_enable(pdev); | ||
54 | * | ||
55 | * This allows other architectures that don't use similar device_enable()/ | ||
56 | * device_shutdown() functions to execute normally. | ||
57 | * | ||
58 | * ... | ||
59 | * | ||
60 | * Suggested usage by device drivers: | ||
61 | * | ||
62 | * During device initialization: | ||
63 | * device_enable() | ||
64 | * | ||
65 | * During device idle: | ||
66 | * (save remaining device context if necessary) | ||
67 | * device_idle(); | ||
68 | * | ||
69 | * During device resume: | ||
70 | * device_enable(); | ||
71 | * (restore context if necessary) | ||
72 | * | ||
73 | * During device shutdown: | ||
74 | * device_shutdown() | ||
75 | * (device must be reinitialized at this point to use it again) | ||
76 | * | ||
