You have to add #include <linux/device.h> into mfd/mcp.h. This will add
struct device and...

struct device_driver.

Same here, the file ucb1x00.h needs #include <linux/device.h>.

#include <linux/pm.h> into collie_battery.c

Thanks,

I don't see anywhere in the driver which would need platform_device.h...
But pm.h, yes.
