[U-Boot] [PATCH v2 3/6] ARM: dts: at91: Add dts files for at91sam9m10g45ek
Wenyou Yang
wenyou.yang at atmel.com
Fri Apr 14 01:11:21 UTC 2017
The device tree source files of at91sam9m10g45ek 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 to determine which nodes
are used by the board_init_f stage.
- Fix the compilation warnings.
