From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tony Lindgren Subject: [PATCH 12/17] ARM: dts: Add missing aess node and binding for omap4 Date: Mon, 28 Aug 2017 14:19:13 -0700 Message-ID: <20170828211918.11573-13-tony@atomide.com> References: <20170828211918.11573-1-tony@atomide.com> Return-path: In-Reply-To: <20170828211918.11573-1-tony-4v6yS6AI5VpBDgjK7y7TUQ@public.gmane.org> Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-omap-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: =?UTF-8?q?Beno=C3=AEt=20Cousson?= , devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Liam Girdwood , Mark Brown , Peter Ujfalusi List-Id: devicetree@vger.kernel.org On omap4 we're missing the aess node with it's related "ti,hwmods" property that the SoC interconnect code needs. Note that this will only show up as a bug with "doesn't have mpu register target base" boot errors when the legacy platform data is removed.
