In order to make it more convenient to pass platform-specific NAND stuff
to a generic driver which is hopefully to come out next, I've introduced
a container structure for chip-specific and controller-specific data.
I'd expect that use cases in platform code will be like
struct platform_nand_data nand_data = {
...
};
struct platform_device nand_device = {
...
.dev = {
.platform_data = &nand_data,
...
},
};
So, please find the patch below.
