From mboxrd@z Thu Jan 1 00:00:00 1970 From: tony@atomide.com (Tony Lindgren) Date: Wed, 20 Sep 2017 15:46:20 -0700 Subject: [PATCH 09/10] ARM: dts: Configure SmartReflex only to idle the interconnect target module In-Reply-To: <20170920224621.16236-1-tony@atomide.com> References: <20170920224621.16236-1-tony@atomide.com> Message-ID: <20170920224621.16236-10-tony@atomide.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The TRM has marked dra7 SmartReflex as reserved and we should not touch those registers as pointed out by Nishanth Menon . We do still want to idle the related interconnect target modules on init though. Let's do this by only configuring the generic interconnect target modules and not add the child SmartReflex devices.
