- 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 130 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 160 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 160 and
- above.
