| 4 | Documentation/devicetree/bindings/clock/clock-bindings.txt | ||
| 5 | |||
| 6 | The CAR (Clock And Reset) Controller on Tegra is the HW module responsible | ||
| 7 | for muxing and gating Tegra's clocks, and setting their rates. | ||
| 8 | |||
| 9 | Required properties : | ||
| 10 | - compatible : Should be "nvidia,tegra20-car" | ||
| 11 | - reg : Should contain CAR registers location and length | ||
| 12 | - clocks : Should contain phandle and clock specifiers for two clocks: | ||
| 13 | the 32 KHz "32k_in", and the board-specific oscillator "osc". | ||
| 14 | - #clock-cells : Should be 1. | ||
| 15 | In clock consumers, this cell represents the clock ID exposed by the CAR. | ||
| 16 | |||
| 17 | The first 96 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB | ||
| 18 | registers. These IDs often match those in the CAR's RST_DEVICES registers, | ||
| 19 | but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In | ||
| 20 | this case, those clocks are assigned IDs above 95 in order to highlight | ||
| 21 | this issue. Implementations that interpret these clock IDs as bit values | ||
| 22 | within the CLK_OUT_ENB or RST_DEVICES registers should be careful to | ||
| 23 | explicitly handle these special cases. | ||
| 24 | |||
| 25 | The balance of the clocks controlled by the CAR are assigned IDs of 96 and | ||
| 26 | above. | ||
