Merge branch 'socfpga/hw' into next/soc
From Dinh Nguyen, this is a series of patches introducing support for
socfpga hardware (Altera Cyclone5). It also includes a cleanup that
moves some of the ARMv7 cache maintenance functions to a common location,
since three other platforms aready implemented it separately.
* socfpga/hw:
arm: socfpga: Add SMP support for actual socfpga harware
arm: Add v7_invalidate_l1 to cache-v7.S
arm: socfpga: Add entries to enable make dtbs socfpga
arm: socfpga: Add new device tree source for actual socfpga HW
Trivial conflict in arch/arm/mach-tegra/headsmp.S.

+NVIDIA Tegra20 Clock And Reset Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
+for muxing and gating Tegra's clocks, and setting their rates.
+
+Required properties :
+- compatible : Should be "nvidia,tegra20-car"
+- reg : Should contain CAR registers location and length
+- clocks : Should contain phandle and clock specifiers for two clocks:
+ the 32 KHz "32k_in", and the board-specific oscillator "osc".
+- #clock-cells : Should be 1.
+ In clock consumers, this cell represents the clock ID exposed by the CAR.
+
+ The first 96 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ this case, those clocks are assigned IDs above 95 in order to highlight
+ this issue. Implementations that interpret these clock IDs as bit values
+ within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ explicitly handle these special cases.
+
+ The balance of the clocks controlled by the CAR are assigned IDs of 96 and
+ above.

- * Guidelines for usage by driver authors:

- * 1. These functions are intended to be used by device drivers via
- * function pointers in struct platform_data. As an example,
- * omap_device_enable() should be passed to the driver as
- *
- * struct foo_driver_platform_data {
- * ...
- * int (*device_enable)(struct platform_device *pdev);
- * ...
- * }
- *
- * Note that the generic "device_enable" name is used, rather than
- * "omap_device_enable". This is so other architectures can pass in their
- * own enable/disable functions here.
- *
- * This should be populated during device setup:
- *
- * ...
- * pdata->device_enable = omap_device_enable;
- * ...
- *
- * 2. Drivers should first check to ensure the function pointer is not null
- * before calling it, as in:
- *
- * if (pdata->device_enable)
- * pdata->device_enable(pdev);
- *
- * This allows other architectures that don't use similar device_enable()/
- * device_shutdown() functions to execute normally.
- *
- * ...
- *
- * Suggested usage by device drivers:
- *
- * During device initialization:
- * device_enable()
- *
- * During device idle:
- * (save remaining device context if necessary)
- * device_idle();
- *
- * During device resume:
- * device_enable();
- * (restore context if necessary)
- *
- * During device shutdown:
- * device_shutdown()
- * (device must be reinitialized at this point to use it again)

ToDo list (incomplete, unordered)
- add compile as module support
- - fix clk usage
- should not be using clk_get_sys(), but clk_get(&pdev->dev, conn)
- where conn is either NULL if the device only has one clock, or
- the device specific name if it has multiple clocks.
- move half of the nvec init stuff to i2c-tegra.c
- move event handling to nvec_events
- finish suspend/resume support
