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 'firmware-name' property which 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
https://lore.kernel.org/linux-devicetree/20220414192722.2978837-1-dfustini@xxxxxxxxxxxx/
Changes from v2:
- correct the name of the property in the commit message of the bindings
patch to firmware-name instead of the old ti,scale-data-fw property
Changes from v1:
- change 'ti,scale-data-fw' to 'firmware-name'
- add 'firmware-name' property to the examples
