12description: |
13  The X1E80100 SPMI PMIC Arbiter implements HW version 7 and it's an SPMI
14  controller with wrapping arbitration logic to allow for multiple on-chip
15  devices to control up to 2 SPMI separate buses.
16
17  The PMIC Arbiter can also act as an interrupt controller, providing interrupts
18  to slave devices.
