+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.

- * of cache lines with uninitialized data and uninitialized tags to get
- * written out to memory, which does really unpleasant things to the main
- * processor. We fix this by performing an invalidate, rather than a
- * clean + invalidate, before jumping into the kernel.

- * In the medium- to long-term, this code should either be

+ * In the medium- to long-term, this code should be implemented as a
+ * proper omap_bus/omap_device in Linux, no more platform_data func
+ * pointers
*
*
- * 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)
- *

* @pwrdm_disable_hdwr_sar: Disable Hardware Save-Restore feature for a pd
* @pwrdm_set_lowpwrstchange: Enable pd transitions from a shallow to deep sleep
* @pwrdm_wait_transition: Wait for a pd state transition to complete
+ *
+ * Regarding @pwrdm_set_lowpwrstchange: On the OMAP2 and 3-family
+ * chips, a powerdomain's power state is not allowed to directly
+ * transition from one low-power state (e.g., CSWR) to another
+ * low-power state (e.g., OFF) without first waking up the
+ * powerdomain. This wastes energy. So OMAP4 chips support the
+ * ability to transition a powerdomain power state directly from one
+ * low-power state to another. The function pointed to by
+ * @pwrdm_set_lowpwrstchange is intended to configure the OMAP4
+ * hardware powerdomain state machine to enable this feature.

- *
- * This funciton is cloned from arch/arm/mach-tegra/headsmp.S, and needs
