Subject: [PATCH v2] ARM: i.MX6: add more chip revision support
Date: Tue, 22 Jul 2014 12:32:54 +0800 [thread overview]
Message-ID: <1406003574-4977-1-git-send-email-shawn.guo@freescale.com> (raw)
From: Jason Liu <r64343@freescale.com>
Add more revision support for the new i.MX6DQ tape-out (TO1.5). This
TO1.5 is the Rev 1.3 as documented in i.MX6DQ data sheet, because TO1.3
and TO1.4 are never revealed.
Signed-off-by: Jason Liu <r64343@freescale.com>

Changes since v1:
- Add a note in code for the numbering mismatch between code and
data sheet
- Fix a typo of tape-out in commit log
