Subject: [PATCH] ARM: DRA752: Add ID detect for ES2.0
Date: Thu, 13 Aug 2015 09:32:20 -0500	[thread overview]
Message-ID: <1439476340-20141-1-git-send-email-nm@ti.com> (raw)

From: Vishal Mahaveer <vishalm@ti.com>

ES2.0 is a minor variant of ES1.1. ES2.0 is an incremental revision
with various fixes including the following:
	- reset logic fixes
	- few assymetric aging logic fixes
	- MMC clock rate fixes
	- Ethernet speed fixes
	- edma fixes for mcasp

NOTE: even though we use a compatible of dra742 and dra752, the usage in
the Linux kernel is more or less interchangable - we use dra752 more
often in the linux kernel compared to dra742 and 4.2-rc6

based on linux-next next-20150812, applies to v4.2-rc6 as well.
Definetly not a 4.2 material, for 4.3, this probably missed the first merge
window for 4.3, will be great if it could be considered for the second merge
window.
