From 972bc90ed8f6008f5e2d42c72d894b2401736519 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 18 Nov 2016 12:23:46 +0530 Subject: OPP: Allow OPP table to be used for power-domains Power-domains can also have their active states and this patch enhances the OPP binding to define those. The power domains can use the OPP bindings as is, with one additional change to Allow "operating-points-v2" property to contain multiple phandles for power domain providers providing multiple domains.

The OPP core will use this phandle to find the operating points for the device. +This can contain more than one phandle for power domain providers that provide +multiple power domains. That is, one phandle for each power domain. If only one +phandle is available, then the same OPP table will be used for all power domains +provided by the power domain provider. + If required, this can be extended for SoC vendor specific bindings. Such bindings should be documented as Documentation/devicetree/bindings/power/-opp.txt and should have a compatible description like: "operating-points-v2-". -- cgit
