From f9a1e9f8cc12ec5d68a009b9287633c6995b8920 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Thu, 11 Jun 2015 18:30:37 +0800 Subject: [PATCH] imx: mx6 introuduce macro is_mx6dqp Add a new revision CHIP_REV_2_0. Introudce macro is_mx6dqp, dqp means Dual/Quad Plus. Since Dual/Quad Plus use same cpu type with Dual/Quad, but different revision(Major Lower), we use this macro for Dual/Quad Plus.
