Subject: [RFC][PATCH] devicetree: Add DTS file to support the Nexus7 2013 (flo) device.
This patch adds a dts file to support the Nexus7 2013
device. Its based off of the qcom-apq8064-ifc6410.dts
which is similar hardware.
Also includes some comments and context folded in
from Vinay Simha BN <simhavcs@...il.com>
This is my first DTS submission, so thoughts or feedback
on would be appreciated.
