From 2a26d31b1bae5d07b97fc05755053295da686ec7 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 31 May 2017 15:51:36 -0700 Subject: [PATCH] ARM: OMAP2+: Remove unused legacy code for PRM We are now booting all mach-omap2 in device tree only mode. Any code that is only called in legacy boot mode where of_have_populated_dt() is not set is safe to remove now.
