[U-Boot] [PATCH 6/6] ARM: dts: at91: Add dts files for at91sam9263ek

12 Apr 2017

The device tree source files of at91sam9263ek 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, pioD, pioE) nodes as the pinctrl's
   slibling nodes, instead of the child nodes.
 - Add the "u-boot,dm-pre-reloc" property for the dbgu node are used
   in board_init_f stage.
 - Fix the compilation warnings.
