ARM: at91: dt: sam9261: Device Tree support for the at91sam9261ek
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 <jjhiblot@traphandler.com> Acked-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
