title: Freescale i.MX7 System Reset Controller

maintainers:

description: |
  The system reset controller can be used to reset various set of
  peripherals. Device nodes that need access to reset lines should
  specify them as a reset phandle in their corresponding node as
  specified in reset.txt.

  For list of all valid reset indices see
    <dt-bindings/reset/imx7-reset.h> for i.MX7,
    <dt-bindings/reset/imx8mq-reset.h> for i.MX8MQ, i.MX8MM and i.MX8MN,
    <dt-bindings/reset/imx8mp-reset.h> for i.MX8MP.
