I don't understand your end goal here...
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.
