[U-Boot] [PATCH v3 00/18] misc: Add AVS class 0 support for AM6

[Keerthy]

Adaptive Voltage Scaling is a technology used in TI SoCs to optimize
the operating voltage based on characterization data written to efuse
during production.

Add support for Adaptive Voltage scaling class 0 support
for AM6 family of devices. Adaptive voltage scaling class 0
implies that optimized voltage values for a particular OPP
of a particular voltage domain are read from Efuse and programmed
on the pmic/regulator.

Tested on AM654-EVM for MPU @800 MHz.
Tested on J721e-evm for MPU.

The series is based on top of the branch:

https://github.com/lokeshvutla/u-boot/tree/devel/j721e-full-boot

Changes in v3:

  * Extended the support for j721e-evm.
  * Moved vtm node under r5-board dts.

Changes in v2:

  * Avoided creation of new uclass. AVS driver is now under misc.
