[POWERPC] Souped-up of_platform_device support This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

[POWERPC] Enable RTC for Ebony and Walnut (v2) This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.
