From bfab07ee52a257b14529264bea908ba0382328ac Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 16 Dec 2019 14:41:53 -0800 Subject: [PATCH] ARM: dts: Configure interconnect target module for omap3 sdma 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. Note that we want to use separate compatible for omap34xx and omap36xx so let's do that here too while at it.
