From 9fd5401659c34b9b07f5d729ad35611b002830ff Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 27 Aug 2015 19:37:11 +0200 Subject: omap5: omap_die_id support This introduces omap5 support for omap_die_id, which matches the common omap_die_id definition. It replaces board-specific code to grab the die id bits.
