From: Bartosz Golaszewski <redacted> We now support board files in the aemif driver. Register a platform device instead of using the handcrafted API in da830-evm.

Actually, now that I've thought about it some more. It probably makes more sense to make all of the "davinci_nand" devices in this series use id = -1 since there is only one per board. It looks like da850 is the only one that has a lookup for "davinic_nand.0" already. I think that we are going to have to add clock lookups for the "davinci_nand" devices as well. Although the driver doesn't do clk_get() explicitly, I think some function it calls does get a clock. I remember that we had to add a clock-ranges property to device tree to get the davinci_nand driver working, which is why I think we are going to need a clock lookup for these devices as well.
