[PATCH 1/1] ARM: DTS: OMAP4: Add OMAP4 Blaze Tablet support
Ruslan Bilovol

Mon Feb 18 07:41:57 EST 2013
The OMAP4 Blaze Tablet is TI OMAP4 processor-based
development platform in a tablet formfactor.
The platform contains many of the features found in
present-day handsets (such as audio, video, wireless
functions and user interfaces) and in addition
contains features for software development and test.
This patch adds initial support for the OMAP4 Blaze
Tablet development platform. Additional functionality
depends on different drivers and code modifications that
are not upstreamed yet or do not support DT yet, so will
be added later.
