Subject: [PATCH 3/5] ARM: dts: omap4: Probe watchdog 3 with ti-sysc
Date: Sun,  8 Jul 2018 23:36:10 -0700	[thread overview]
Message-ID: <20180709063612.12025-4-tony@atomide.com> (raw)
In-Reply-To: <20180709063612.12025-1-tony@atomide.com>

Before updating wdt2 to probe with ti-sysc we want to have wdt3
probed with ti-sysc to avoid having them unnecessarily swap order.

With ti-sysc, we probe child devices at module_init time while
and until l4 abe interconnect is converted to use ti-sysc, wdt3
will probe earlier with legacy platform data.
