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

[Drew Fustini]

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.
