#1404023 — [PATCH v2 3/3] ARM: dts: rockchip: fixes the spi compatible for rk3036

That's seem the incorrect string to match the spi driver.

Fixes commit f629fcfab2cd

Will it break the backward compatibility for some dtb if not
falling back to "rockchip,rockchip-spi" ?

The rk3036 shouldn't work if you read the driver/spi/spi-rockchip.c.
since the "rockchip,rockchip-spi" is *not* exist in linux kernel.

..
  static const struct of_device_id rockchip_spi_dt_match[] = {
     { .compatible = "rockchip,rk3066-spi", },
     { .compatible = "rockchip,rk3188-spi", },
     { .compatible = "rockchip,rk3288-spi", },
     { .compatible = "rockchip,rk3399-spi", },
     { },
}
..

okay, so that means we take "rockchip,rockchip-spi" from local branch
by mistake?

in what dtb did you see "rockchip,rockchip-spi"?
I.e. it isn't part of any current _mainline_ devicetree files.

I'm not 100% sure, but I remember we toke this name on local
branch for rk3036 when we were developing this Soc.

Caesar, Could you check our develop-3.10 branch to see if it does
exist?

Anyway, "rockchip,rockchip-spi" isn't a part of mainline dt property.
