This series adds Keystone GPIO IP definition in DT and enable GPIO support in
Keystone configuration file.
Also, it enables LEDs support for Keystone 2 K2H EVM as specified in board
schematic. For more information see:
- http://www.advantech.com/Support/TI-EVM/EVMK2HX.aspx
Changes in v3:
- rebased on top 3.14 + "[PATCH v2] arm: dts: keystone: add watchdog entry"
http://www.spinics.net/lists/devicetree/msg20211.html
[v1-v2] http://www.spinics.net/lists/arm-kernel/msg294655.html
Grygorii Strashko (4):
ARM: dts: keystone: add gpio device entry
ARM: dts: keystone-evm: add leds supports
ARM: keystone_defconfig: enable gpio support
ARM: keystone_defconfig: enable led support
