+
+maintainers:
+ - Peng Fan <peng.fan@nxp.com>
+
+description: |
+ The System Reset Controller (SRC) is responsible for the generation of
+ all the system reset signals and boot argument latching.
+
+ Its main functions are as follows,
+ - Deals with all global system reset sources from other modules,
+ and generates global system reset.
+ - Responsible for power gating of MIXs (Slices) and their memory
+ low power control.
