This may even be recursively like on most Rockchip boards using the act8846 where REG4 is most of the time connected to the inl1-supply. Therefore add the ability to specify the input supplies for the individual inputs. The input-names are taken from the datasheets of both act8846 and act8865.

The recursive supplies are very common - DCDCs are vastly more efficient than LDOs so if you've got the capacity and care about power it's much better to drop your main supply voltage down to something near the LDO headroom with a DCDC in order to improve system performance. -------------- next part -------------- A non-text attachment was scrubbed...
