From f60c41257fa06d496c9653d3f77d34b7426d9274 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 12 Dec 2019 09:46:09 -0800 Subject: [PATCH] ARM: dts: Configure interconnect target module for am4 qspi 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.
