Subject: [PATCH 05/12] ARM: dts: Configure interconnect target module for omap4 debugss
Date: Mon,  8 Mar 2021 15:39:03 +0200	[thread overview]
Message-ID: <20210308133910.12454-6-tony@atomide.com> (raw)
In-Reply-To: <20210308133910.12454-1-tony@atomide.com>

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" property to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.
