From cd57dc5a2099a43c99fb39cb7c953246149db816 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 30 Aug 2017 08:19:52 -0700 Subject: [PATCH] ARM: dts: Add missing hwmod related nodes for am33xx On am33xx we're missing the pmu and emif nodes with their related "ti,hwmods" properties 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. Let's also update the related binding documentation while at it.
