From 941f2fcc5bc66aceb993032a05641248eb092e11 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 29 Dec 2017 11:47:51 +0530 Subject: [PATCH] arm: dra762: Add support for device package identification DRA762 comes in two packages: - ABZ: Pin compatible package with DRA742 with DDR@1333MHz - ACD: High performance(OPP_PLUS) package with new IPs Both the above packages uses the same IDCODE hence needs to differentiate using package information in DIE_ID_2. Add support for the same. Also update clock, ddr, emif information.
