[U-Boot] [PATCH 1/2] ARM: dts: at91: add dts files for at91sam9261ek
Wenyou Yang

Mon Feb 27 03:29:42 UTC 2017
The device tree source files of at91sam9261ek boards are copied
from the Linux v4.10, do the changes as below.
- Add the reg property for the pinctrl node.
- Move the gpio (pioA, pioB, pioC) nodes as the pinctrl's slibling
nodes, instead of the child nodes.
- Fix the compilation warnings.
