From 302502efaf8fa0f553634b736723e1f9aedbda10 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 16 Nov 2020 12:57:13 +0200 Subject: [PATCH] ARM: dts: Configure interconnect target module for am4 wkup_m3 We can now probe devices with device tree only configuration using ti-sysc interconnect target module driver. Note that we no longer need ti,no-reset-on-init as the rstctrl resets are properly handled by the reset driver and claimed by the RTC driver. And we need to squash together the module ranges for driver compability.
