NVIDIA Tegra124 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,tegra124-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 assignments may be found in header file
<dt-bindings/clock/tegra124-car.h>.
Example SoC include file:
/ {
tegra_car: clock {
compatible = "nvidia,tegra124-car";
reg = <0x60006000 0x1000>;
#clock-cells = <1>;
};
usb@c5004000 {
clocks = <&tegra_car TEGRA124_CLK_USB2>;
};
};
Example board file:
/ {
clocks {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <0>;
osc: clock@0 {
compatible = "fixed-clock";
reg = <0>;
#clock-cells = <0>;
clock-frequency = <112400000>;
};
clk_32k: clock@1 {
compatible = "fixed-clock";
reg = <1>;
#clock-cells = <0>;
clock-frequency = <32768>;
};
};
&tegra_car {
clocks = <&clk_32k> <&osc>;
};
};

* This header provides constants for binding nvidia,tegra124-car.
*
* The first 192 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 185 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 185 and
* above.
