[v1 0/2] Add DTS for BPI-R3
From: Frank Wunderlich frank-w@public-files.de
Add board specific devicetree for BananaPi R3.
It is taken from openwrt https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/boot/uboot-m... only enabled the factory button which was disabled because a HW-bug in rev 1.0 of r3.

Hi
noticed that i need to change the label of wps button back to "wps" when enabling the factory button (else there will be 2 buttons with same label).

- keys {
compatible = "gpio-keys";factory {label = "reset";gpios = <&gpio 9 GPIO_ACTIVE_LOW>;};wps {label = "reset";
label was changed in openwrt to use this button for reset, but hw bug fixed in newer v1.1 versions of the board. I will change this to "wps" like in linux in next version.
just tell me if the structure is right or if there any other things need to be changed.
gpios = <&gpio 10 GPIO_ACTIVE_LOW>;};- };
regards Frank

Use own devicetree for the board and change the prompt.
