Subject: [PATCH v2 0/2] soc: ti: wkup_m3_ipc: Add support for IO Isolation

TI AM437x SoCs support isolation of the IOs so that control is taken
from the peripheral they are connected to and overridden by values
present in the control register for that pad. This series documents a
new property 'ti,set-io-isolation' and updates the wkup_m3_ipc driver to
inform the CM3 firmware when that property is set.

A prerequisite for this series is:
[PATCH v2 0/2] soc: ti: wkup_m3_ipc: support vtt toggle
https://lore.kernel.org/lkml/20220409211215.2529387-1-dfustini@baylibre.com/T/

Changes from v1:
- correct typo of 'ti,set-io-isolation' property
- make 'ti,set-io-isolation' only valid for 'ti,am4372-wkup-m3-ipc'
