1 NVIDIA Tegra124 and Tegra132 Clock And Reset Controller
3 This binding uses the common clock binding:
4 Documentation/devicetree/bindings/clock/clock-bindings.txt
6 The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
10 - compatible : Should be "nvidia,tegra124-car" or "nvidia,tegra132-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
17   <dt-bindings/clock/tegra124-car-common.h> (which covers IDs common
18   to Tegra124 and Tegra132) and <dt-bindings/clock/tegra124-car.h>
19   (for Tegra124-specific clocks).
20 - #reset-cells : Should be 1.
21   In clock consumers, this cell represents the bit number in the CAR's
23 - nvidia,external-memory-controller : phandle of the EMC driver.
25 The node should contain a "emc-timings" subnode for each supported RAM type (see
28 Required properties for "emc-timings" nodes :
29 - nvidia,ram-code : Should contain the value of RAM_CODE this timing set
32 Each "emc-timings" node should contain a "timing" subnode for every supported
33 EMC clock rate.
36 - clock-frequency : Should contain the memory clock rate to which this timing
38 - nvidia,parent-clock-frequency : Should contain the rate at which the current
39 parent of the EMC clock should be running at this timing.
40 - clocks : Must contain an entry for each entry in clock-names.
41   See ../clocks/clock-bindings.txt for details.
42 - clock-names : Must include the following entries:
43   - emc-parent : the clock that should be the parent of the EMC clock at this
