From f2c199db477efd8233e75b2d69bac8be8640308d Mon Sep 17 00:00:00 2001 From: Guy Shapiro Date: Tue, 7 Feb 2017 17:56:05 +0200 Subject: power: reset: syscon-poweroff: add a mask property Make the syscon-poweroff driver accept value and mask instead of just value. Prior to this patch, the property name for the value was 'mask'. If only the mask property is defined on a node, maintain compatibility by using it as the value.
