From 9f20d6815c6c537980b8a8fcb1a172c0b95bd99f Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 22 Jun 2015 14:23:27 +0200 Subject: [PATCH] PM / OPP: Add binding for 'opp-suspend' On few platforms, for power efficiency, we want the device to be configured for a specific OPP while we put the device in suspend state. Add an optional property in operating-points-v2 bindings for that. Suggested-by: Nishanth Menon Signed-off-by: Viresh Kumar Acked-by: Nishanth Menon Acked-by: Rob Herring Signed-off-by: Rafael J.
