[PATCH 0/2] soc: ti: wkup_m3_ipc: support i2c voltage scaling

From: Drew Fustini
Date: Mon Apr 25 2022 - 01:29:51 EST

Allow loading of a binary file containing i2c scaling sequences to be
provided to the Cortex-M3 firmware in order to properly scale voltage
rails on the PMIC during low power modes like DeepSleep0.

The new 'ti,scale-data-fw' property contains the name of a binary file.

A prerequisite for this series is:
[PATCH v3 0/2] soc: ti: wkup_m3_ipc: Add support for IO Isolation

Dave Gerlach (2):
dt-bindings: wkup-m3-ipc: Add ti,scale-data-fw property
soc: ti: wkup_m3_ipc: Add support for i2c voltage scaling
