[PATCH v2 1/3] spi/rockchip: add rk3036/rk3228/rk3368 SoCs for spi document

[PATCH v2 1/3] spi/rockchip: add rk3036/rk3228/rk3368 SoCs for spi document

[Caesar Wang]

We had supported the rk3036/rk3066/rk3188/rk3228/rk3288/rk3368/rk3399
family SoCs in linux kernel.

Let's add the other SoCs, in order to a better understanding from the
rockchip spi document.

[PATCH v2 2/3] spi/rockchip: add the rk3036/rk3228/rk3368 to match for driver

[Caesar Wang]

In gerenal, the "rockchip,rockchip-spi" string will match the dts
that's great in spi driver. After all the most of rockchip SoCs ar
same spi controller.

Then, we should keep the old style to match the dts various.

Will it break the backward compatibility for some dtb if not

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?

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.
