The of-platdata feature allows driver model to be used in SPL without the overhead of a devicetree. The relevant parts of the devicetree are converted to C by the dtoc tool.
So far of-platdata supports various drivers but not enough to support the am335x boards.
This series adds GPIO support to of-platdata, via a gpio_request_by_phandle() function which looks up GPIOs from the of-platdata information.
It also tidies up the existing clock support and finishes off irq support.
Finally it includes a new OF_REAL symbol to control whether a devicetree is actually available at runtime. This allows some simplification of the #ifdef logic.
For am335x, the cpsw driver uses several devicetree subnodes. For this to work with dtoc it needs to be converted to separate drivers for each subnode, each with a compatible string.
