[PATCH 00/11] soc: ti: wkup_m3_ipc: support vtt toggle, io isolation & voltage scaling

From: Drew Fustini
Date: Sat Feb 19 2022 - 16:55:55 EST


Improve the wkup_m3_ipc driver to better support the TI Wakeup Cortex M3
device found on TI AM33xx and AM43xx SoCs.

This series derives from these commits in the ti-linux-5.10.y branch of
the TI Linux repo [1]:

6ab4eff1034b ("remoteproc: move rproc_da_to_va declaration to remoteproc.h")
2a9be39a26f7 ("dt-bindings: wkup_m3_ipc: Add vtt toggling bindings")
c65263f9e12c ("wkup_m3_ipc: Add support for toggling VTT regulator")
5c6c821803e1 ("dt-bindings: wkup_m3_ipc: Add ti,io-isolation property")
196c46f7577d ("wkup_m3_ipc: Add support for IO Isolation")
c28acc847e5d ("soc: ti: wkup_m3_ipc: Add support for i2c voltage scaling")
a4f9ef4ab5ca ("ARM: dts: am437x-gp-evm: Enable wkup_m3 control of IO isolation")
94de756f1771 ("ARM: dts: am33xx: Add scale data fw to wkup_m3_ipc node")
b7ae4b063793 ("ARM: dts: am43xx: Add scale data fw to wkup_m3_ipc node")
451ec7871ae7 ("soc: ti: wkup_m3_ipc: Add debug option to halt m3 in suspend")

Minor changes have been made to some patches to resolve conflicts and
to split i2c voltage scaling dt-bindings into separate patch.
