title: Qualcomm X1E80100 SPMI Controller (PMIC Arbiter v7)

maintainers:
  - Stephen Boyd <sboyd@kernel.org>

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