I'm a little confuse, I have upstreamed rockchip-i2s, and the i2s driver
set the compatible like:
- compatible: should be one of the followings
- "rockchip,rk3066-i2s": for rk3066
- "rockchip,rk3188-i2s", "rockchip,rk3066-i2s": for rk3188
- "rockchip,rk3288-i2s", "rockchip,rk3066-i2s": for rk3288
- "rockchip,rk3399-i2s", "rockchip,rk3066-i2s": for rk3399
and the driver only has
static const struct of_device_id rockchip_i2s_match[] = {
{ .compatible = "rockchip,rk3066-i2s", },
{},
};
The spi of rk3399 as same as rk3066, rk3188, rk3288, like i2s, if they
are keep different rules ?
