[PATCH 5/6] ARM: tegra114: create a DT header defining CLK IDs

Hiroshi Doyu hdoyu at nvidia.com
Mon May 13 21:07:04 EST 2013


Replace magic number in tegra_car:

-               clocks = <&tegra_car 28>;
+               clocks = <&tegra_car CLK_HOST1X>;

 The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
 for muxing and gating Tegra's clocks, and setting their rates.

 - #clock-cells : Should be 1.
   In clock consumers, this cell represents the clock ID exposed by the CAR.
 
-  The first 160 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
