From a06ccd9c3785fa5550917ae036944f4e080b5749 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Tue, 15 Oct 2013 20:14:20 +0100 Subject: regulator: core: Add ability to create a lookup alias for supply These patches add the ability to create an alternative device on which a lookup for a certain supply should be conducted. A common use-case for this would be devices that are logically represented as a collection of drivers within Linux but are are presented as a single device from device tree. It this case it is necessary for each sub device to locate their supply data on the main device.
