4bb2d1009f ARM: More SoC support updates
This branch contains a handful of updates of SoC base code that had
 dependencies on other external trees that have now been merged:
 
 * Support for the new EXYNOS5250 SoC from Samsung
 * SMP and power domain support for Tegra3 from NVIDIA
 * ux500 updates for exporting SoC information through sysfs

34800598b2 ARM: driver specific updates
These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

35b1498a34 ARM: tegra: cleanup use of chipid register
The chipid register contains information about the Tegra variant and revision.
We want differentiate between Tegra variants for powergating and secondary
core bringup. This patch cleans up the reading and decoding of this register.
In subsequent patches the variant will exported as a global variable.

9a1086da34 ARM: tegra: fuse: add functions to access chip revision
Add function to get chip revision, and print it out at boot time.

Restructure the fuse access to just use cached variables instead
of always reading the fuses, and export those variables directly
instead of using accessor functions.

Add a SKU ID table of currently known values.

Based on code originally by Colin Cross <ccross@android.com>.

Changes since v1:

* Add A01 minor rev support
* Don't decode for A03p on anything but T2x
