+title: Freescale i.MX8qm/qxp Control and Status Registers Module
+
+maintainers:
+ - Liu Ying <victor.liu@nxp.com>
+
+description: |
+ As a system controller, the Freescale i.MX8qm/qxp Control and Status
+ Registers(CSR) module represents a set of miscellaneous registers of a
+ specific subsystem. It may provide control and/or status report interfaces
+ to a mix of standalone hardware devices within that subsystem. One typical
+ use-case is for some other nodes to acquire a reference to the syscon node
+ by phandle, and the other typical use-case is that the operating system
+ should consider all subnodes of the CSR module as separate child devices.
