The PCI hardware is CS5535/CS5536 based, and the device that it grabs is handled by the cs5535-mfd driver. This converts the SCx200 driver to use a platform_driver rather than the previous PCI hackery. The driver used to manually track the iface list (via linked list); now it only does this for ISA devices. PCI ifaces are handled through standard driver model lists. It's unclear what happens in case of errors in the old ISA code; rather than pretending the code actually cares, I've dropped the (implicit) ignorance of return values and marked it with a comment.

If "rtc_delay" field of the platform data is true, the rtc driver assumes that such delays are required. Although we have not seen LP3974s without requiring such delays, we assume that such LP3974s will be released soon (or they have done so already) and they are supported by "lp3974" without setting "rtc_delay" at the platform data. This patch adds delays with msleep when writing values to RTC registers if the platform data has rtc_delay set.
