description:
The MediaTek MT8196 SoC features a SPMI version 2.0 compliant controller,
with internal wrapping arbitration logic to allow for multiple on-chip
devices to control up to two SPMI buses.
The main arbiter also acts as an interrupt controller, arbitering also
the interrupts coming from SPMI-connected devices into each of the nested
interrupt controllers from any of the present SPMI buses.
