Subject: [PATCH 0/3] drivers: bus: Add Freescale i.MX8qxp pixel link MSI bus support
Date: Tue, 2 Aug 2022 15:13:07 +0800 [thread overview]
Message-ID: <20220802071310.2650864-1-victor.liu@nxp.com> (raw)
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.
