Driver Core: Add platform device arch data V3
Allow architecture specific data in struct platform_device V3. With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices. [rjw: This change is for power management mostly and that's why it goes through the suspend tree.] Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Rafael J.
