Subject: [v3 2/6] ARM: tegra20: convert device tree files to use CLK defines
Replace magic number in tegra_car:
- clocks = <&tegra_car 28>;
+ clocks = <&tegra_car CLK_HOST1X>;

- #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.
