SPMI Controller Simulator
|
||
|
|
|
||
|
|
The SPMI Controller Simulator simulates an SPMI bus with PMIC devices attached
|
||
|
|
to it.
|
||
|
|
|
||
|
|
See spmi.txt for the generic SPMI controller binding requirements for child
|
||
|
|
nodes.
|
||
|
|
|
||
|
|
Supported Properties:
|
||
|
|
|
||
|
|
- compatible
|
||
|

|
- reg
|
||
|
|
Usage: required
|
||
|
|
Value type: <prop-encoded-array>
|
||
|
|
Definition: List of SPMI address and size pairs. These addresses are
|
||
|
|
the ones to be simulated.

|
|
- interrupt-controller
|
||
|
|
Usage: required
|
||
|
|
Value type: boolean
|
||
|
|
Definition: Boolean indicating that the SPMI Controller Simulator is an
|
||
|
|
interrupt controller.
|
||
|
|
|
||
|
|
- #interrupt-cells
|
||
|
|
Usage: required
|
||
|
|
Value type: <u32>
|
||
|
|
Definition: Must be 4.
|
||
|
|
Interrupts are specified as a 4-tuple:
|
||
|
|
Cell 1: Slave ID for the requested interrupt (0-15)
|
||
|
|
Cell 2: Peripheral ID for requested interrupt (0-255)
|
||
|
|
Cell 3: The requested peripheral interrupt (0-7)
|
||
|
|
Cell 4: Interrupt flags indicating level-sense
|
||
|
|
information, as defined in:
|
||
|
|
dt-bindings/interrupt-controller/irq.h
|
||
|
|
|
||
|
|
- qcom,reg-defaults
|
||
|
|
Usage: optional
|
||
|
|
Value type: <prop-encoded-array>
|
||
|
|
Definition: List of SPMI address and value pairs. These define the
|
||
|
|
default values read back from the simulated registers. The
|
||
|
|
values must be between 0 and 255.
|
||

|
|
Definition: phandle of the spmi-sim bus device that the simulated PMIC
|
||
|
|
device should be used with.

||
|
|
|
||
|
