Subject: [PATCH v2 0/7] Add input voltage suppliers for PMIC MCP16502 regulators
In this series of patches, support for the *-supply property [1] is added
(correlated with supply_name [2]) from the core regulator.
Link [1]: https://github.com/torvalds/linux/blob/master/drivers/regulator/core.c#L471
Link [2]: https://github.com/torvalds/linux/blob/master/drivers/regulator/core.c#L2064
I modified the mcp16502.c driver and the dts that use this PMIC.
We added these improvements to provide a complete description of the board power scheme.
Snippet (as an example) from /sys/kernel/debug/regulator/regulator_summary
(for at91-sama7g5ek):
# cat regulator_summary

Changelog:
v1 -> v2:
- drop (lvin|pvin[1-4])-supply from each regulators sub-node
- add voltage input supply documentation in the yaml schema
- add lvin-supply, pvin[1-4]-supply to PMIC node
