[PATCH 08/15] ARM: dts: Configure interconnect target module for dra7 mpu

From: Tony Lindgren <tony@atomide.com>
Date: 2021-01-26 12:43:01
Also in: linux-omap, linux-pci
Subsystem: the rest · Maintainer: Linus Torvalds

We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.
