static struct ucb1400_pdata pdata = {
.irq = IRQ_GPIO(123),
};
static struct platform_device ucb1400_core = {
.name = "ucb1400_core",
.id = -1,
.dev = {
.platform_data = &pdata,
},
};
init() {
platform_device_register(&ucb1400_core);
}
Like this ?
btw. you don't have to pass pdata at all ... the logic for auto-detecting IRQ is
still there and is active if no pdata are supplied.
