Bad wording, sorry. The goal is to have a platform driver (as in
platform bus) that will initialize my platform (as in: board, machine,
hardware). My platform (as in: the board) will be represented by the
root platform bus device (as in: the bus ;-) with compatible value
matching the one passed in the device tree's root.
The tree:
8<----------------------------
/ {
compatible = "my,board";
}
8<----------------------------
The driver:
8<----------------------------
static struct of_device_id my_board_match[] = {
{ .compatible = "my,board", },
{},
};
static struct platform_driver my_board_driver = {
.driver = {
.name = "my_board",
.owner = THIS_MODULE,
.of_match_table = of_match_ptr(my_board_match),
},
.probe = my_board_probe,
.remove = my_board_remove,
};
module_platform_driver(my_board_driver);
8<----------------------------
I'll work on better commit message for the next spin.
