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.
