description: |
|
||
|
|
HiSilicon 6421v600 should be connected inside a MIPI System Power Management
|
||
|
|
(SPMI) bus. It provides interrupts and power supply.
|
||
|
|
|
||
|
|
The GPIO and interrupt settings are represented as part of the top-level PMIC
|
||
|
|
node.
|
||
|
|
|
||
|
|
The SPMI controller part is provided by
