From 1dcbae86ee669bdb0338954cd0136863f5c96c0a Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Thu, 14 Apr 2022 12:27:24 -0700 Subject: soc: ti: wkup_m3_ipc: Add support for IO Isolation AM43xx support isolation of the IOs so that control is taken from the peripheral they are connected to and overridden by values present in the CTRL_CONF_* registers for the pad in the control module. The actual toggling happens from the wkup_m3, so use a DT property from the wkup_m3_ipc node to allow the PM code to communicate the necessity for placing the IOs into isolation to the firmware.
