Subject: [PATCH v3 00/11] enable VTM node for all TI's K3 SoCs

Hello again everyone!

This series enables the VTM nodes for all of Texas Instrument's K3 SoCs

Most of this series updates the k3_j72xx_bandgap driver to conditionally 
map an eFuse region used by the j721e to work around an issue in its VTM 
implementation and allows us to save the SPARE_FUSE region on other SoCs

We can then update the device tree bindings for the driver and finally 
define the VTM nodes for each device

Thanks for reviewing again
~Bryan

****

v2 -> v3 changes[0]:

- removed a errant devm_iounmap() I introduced between patches in v2

- collected tags

v1 -> v2 changes[1]:

- when removing 'fuse_base' from the 'k3_j72xx_bandgap' structure, I 
  forgot to pass 'fuse_base' to get_efuse_values() 

- removed the descriptions to the generic 'power-domains' property

- incorporated Krzysztof's suggestions to the binding description

- refactored binding to use allOf: if: {min,max}Items over what I was 
  doing :) Thanks Krzysztof
