| System Power Management Interface (SPMI) Controller |
| |
| This document defines a generic set of bindings for use by SPMI controllers. A |
| controller is modelled in device tree as a node with zero or more child nodes, |
| each representing a unique slave on the bus. |
| |
| Required properties: |
| - #address-cells : must be set to 2 |
| - #size-cells : must be set to 0 |
| |
| Child nodes: |
| |
| An SPMI controller node can contain zero or more child nodes representing slave |
| devices on the bus. Child 'reg' properties are specified as an address, type |
| pair. The address must be in the range 0-15 (4 bits). The type must be one of |
| SPMI_USID (0) or SPMI_GSID (1) for Unique Slave ID or Group Slave ID respectively. |
| These are the identifiers "statically assigned by the system integrator", as |
| per the SPMI spec. |
| |
| Each child node must have one and only one 'reg' entry of type SPMI_USID. |
