at91-sama7g5ek.dtb: mcp16502@5b: regulators:VDD_(CORE|OTHER)|LDO[1-2]:
regulator-state-standby 'regulator-suspend-voltage' does not match any of
the regexes 'pinctrl-[0-9]+' from schema
$id: http://devicetree.org/schemas/regulator/microchip,mcp16502.yaml#

no property named regulator-suspend-voltage in
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/regulator/regulator.yaml  
so if it is using this property there will be no effect as it was expected in 
https://github.com/torvalds/linux/commit/85b1304b9daa06367139b471789c7ddb76250b9f

The main reason is explained in the cover-letter but if you ask me to explain in each commit I will do it in next version.

Yes, in hurry I slipped that "boot" in subject.
