From c8b263cc03eaaa324c9222474191e6d849cb6dda Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sat, 7 Mar 2015 16:33:53 +0100 Subject: regulator: act8865: add input supply handling The act88600/act8846/act8865 regulators have a number of input supplies supplying the individual regulators. 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 act8600, act8846 and act8865. On the act8600 some regulators do not have separate input supplies.
