description:
|
||
|
The Clock Pulse Generator (CPG) can gate SoC device clocks. The gates are
|
||
|
organized in groups of up to 32 gates.
|
||
|
|
||
|
This device tree binding describes a single 32 gate clocks group per node.
|
||
|
Clocks are referenced by user nodes by the Module Stop (MSTP) node phandle
|
||
|
and the clock index in the group, from 0 to 31.
