Subject: [PATCH v3 0/3] drivers: bus: Add Freescale i.MX8qxp pixel link MSI bus support
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.
v2->v3:
* Add a pattern property to allow child nodes in the MSI bus dt-binding. (Rob)
v1->v2:
Address Krzysztof's comments on patch 3:
* Add a select to explicitly select the MSI bus dt-binding.
* List 'simple-pm-bus' explicitly as one item of compatible strings.
* Require compatible and reg properties.
* Put reg property just after compatible property in example.
