[PATCH 0/3] drivers: bus: Add Freescale i.MX8qxp pixel link MSI bus support

[Liu Ying]

Hi,

This series aims to add Freescale i.MX8qxp pixel link MSI bus support
by using the existing simple-pm-bus driver. A power domain and two input
clocks need to be enabled before the MSI bus accesses it's child devices,
which matches what a simple power-managed bus is(See simple-pm-bus.yaml).

Patch 1 adds support to populate simple MFD child devices in the
simple-pm-bus driver, since the MSI bus may connect those devices.

Patch 2 enables/disables functional clock(s) as a bulk in the
simple-pm-bus driver when the simple-pm-bus is being power managed,
since the MSI bus takes the two input clocks as functional clocks.

Patch 3 adds dt-bindings for the MSI bus.
