Subject[PATCH v8 2/2] ARM: dts: TS-4600: add basic device tree
Date
These device trees add support for the TS-4600 by Technologic Systems.

More details here:
http://wiki.embeddedarm.com/wiki/TS-4600

Signed-off-by: Sebastien Bourdelin <sebastien.bourdelin@savoirfairelinux.com>
---
Changes v7 -> v8:
- rebase on master
- merge the rev A and B into one device tree based on the last rev B
because only the memory size change between the two rev currently
(suggested by Shawn Guo)

Changes v6 -> v7:
- rebase on master
- remove unneeded pinctrl-name (suggested by Shawn Guo)
- add reg to the node en-sd-pwr (suggested by Shawn Guo)
- use define for gpio polarity (suggested by Shawn Guo)
- remove the fake bus container for regulator (suggested by Shawn Guo)

Changes v5 -> v6:
- rebase on master
- split the previous patch series into series by subsystem

Changes v4 -> v5:
- fix missing signed off

Changes v3 -> v4:
- rebase on master

Changes v2 -> v3:
- rebase on master

Changes v1 -> v2:
- rebase on master
