This patch implements a DTS to boot a at91sam9261ek with a dt-enabled kernel (at91_dt_defconfig). supported features are: * dbgu * lcdc * usb host * usb gadget, * spi dataflash * nand flash * touchscreen * leds * user buttons
In the TODO list: * dm9000 (ethernet) * audio * mmc Signed-off-by: Jean-Jacques Hiblot <[email protected]> --- arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/at91sam9261ek.dts | 204 ++++++++++++++++++++++++++++++++++++ 2 files changed, 206 insertions(+) create mode 100644 arch/arm/boot/dts/at91sam9261ek.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index b9d6a8b..493082b 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -12,6 +12,8 @@ dtb-$(CONFIG_ARCH_AT91) += ethernut5.dtb dtb-$(CONFIG_ARCH_AT91) += evk-pro3.dtb dtb-$(CONFIG_ARCH_AT91) += tny_a9260.dtb dtb-$(CONFIG_ARCH_AT91) += usb_a9260.dtb +# sam9261 +dtb-$(CONFIG_ARCH_AT91) += at91sam9261ek.dtb # sam9263 dtb-$(CONFIG_ARCH_AT91) += at91sam9263ek.dtb dtb-$(CONFIG_ARCH_AT91) += tny_a9263.dtb diff --git a/arch/arm/boot/dts/at91sam9261ek.dts b/arch/arm/boot/dts/at91sam9261ek.dts new file mode 100644 index 0000000..03adb7f --- /dev/null +++ b/arch/arm/boot/dts/at91sam9261ek.dts @@ -0,0 +1,204 @@ +/* + * at91sam9261ek.dts - Device Tree file for Atmel at91sam9261 reference board + * + * Copyright (C) 2013 Jean-Jacques Hiblot <[email protected]> + * + * Licensed under GPLv2 only. + */ +/dts-v1/;
