  12 description: |
  13   The system reset controller can be used to reset various set of
  14   peripherals. Device nodes that need access to reset lines should
  15   specify them as a reset phandle in their corresponding node as
  16   specified in reset.txt.
  17
  18   For list of all valid reset indices see
  19     <dt-bindings/reset/imx7-reset.h> for i.MX7,
  20     <dt-bindings/reset/imx8mq-reset.h> for i.MX8MQ, i.MX8MM and i.MX8MN,
  21     <dt-bindings/reset/imx8mp-reset.h> for i.MX8MP.
