From 2e18f5a1bc18e8af7031b3b26efde25307014837 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Mon, 7 Mar 2016 01:41:21 -0700 Subject: ARM: OMAP2+: hwmod: Introduce ti,no-idle dt property Introduce a dt property, ti,no-idle, that prevents an IP to idle at any point. This is to handle Errata i877, which tells that GMAC clocks cannot be disabled.
