sorry....i may be wrong.....everyone has a "FIRST-TIME".....
just some remarks:
a. LCD using OMAP? there is a subdirectory drivers/vide/omap which
have a few implementation for LCD drivers. one of them (quite simple
to understand.....because lots of DO-NOTHING....) is lcd_sx1.c......
b. from lcd_sx1.c, the device is seemingly added AFTER
platform_driver _register() is called....contrary to your statement.
c. just the essential shown here:
first the module
struct platform_driver sx1_panel_driver = {
.probe = sx1_panel_probe,
.remove = sx1_panel_remove,
.suspend = sx1_panel_suspend,
.resume = sx1_panel_resume,
.driver = {
.name = "lcd_sx1",
.owner = THIS_MODULE,
},
};
static int sx1_panel_drv_init(void)
{
return platform_driver_register(&sx1_panel_driver);
}
The above will register the probe function. And device registration
is done in probe function:
static int sx1_panel_probe(struct platform_device *pdev)
{
omapfb_register_panel(&sx1_panel);
return 0;
}
Does that answer your query?
