[U-Boot] [PATCH 1/3] ARM: dts: at91: add dts file for at91sam9g20/at91sam9260
Wenyou Yang
wenyou.yang at atmel.com
Wed Feb 22 10:10:45 UTC 2017
The device tree source files of at91sam9g20ek and at91sam9260ek
boards are copied from the Linux v4.10, do the changes below.
- Fix the build error for the usb0 node.
- 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.
- Add the clk pinctrl of the mmc0 node.
- Fix the compile warnings.
