I don't know if that is possible to do in a one call, but maybe using the
approach from mpc52xx_uart might help?
--clip--
for_each_node_by_type(np, "serial") {
if (!of_match_node(mpc52xx_uart_of_match, np))
continue;
/* Is a particular device number requested? */
devno = of_get_property(np, "port-number", NULL);
mpc52xx_uart_of_assign(of_node_get(np), devno ? *devno : -1);
}
--clip--
And change serial->gpt, port-number to cell-index and add some logic to
select the devices you want. Or if you wan't to do it a bit differently you
could add a pseudo device outside the main tree like
mydev {
gpt-dev = <&the_gpt_dev>:
};
And get it that way. However I don't know if this is recommended approach, but
I've used it for some simple stuff like binding gpt in PWM mode to
framebuffer backlight, along with power-pin.
Please correct any mistakes you who know better.
