* [PATCH 0/3] introducing Atmel sama5d2 SoC @ 2015-06-18 13:18 ` Nicolas Ferre 0 siblings, 0 replies; 18+ messages in thread From: Nicolas Ferre @ 2015-06-18 13:18 UTC (permalink / raw) To: linux-arm-kernel Hi, This is a little series to introduce the new Atmel Cortex-A5 sama5d2 SoC. The product is not yet announced so you cannot find the datasheet yet. But be sure to find it when it's released at the usual location: atmel.com! The support is basic for now but allows to boot the chip and use the sama5d2 Xplained board. This series is dependent on other patches sent for clocks (PMC + generic clocks), irqchip and Ethernet. These patches will hopefuly progress as this series goes upstream and is finaly merged in arm-soc. More material is on its way to being published or already under review (like the flexcom for instance). Stay tunned for more fun!

* [PATCH 3/3] ARM: at91/dt: add minimal sama5d2 Xplained board 2015-06-18 13:18 ` Nicolas Ferre @ 2015-06-18 13:18 ` Nicolas Ferre -1 siblings, 0 replies; 18+ messages in thread From: Nicolas Ferre @ 2015-06-18 13:18 UTC (permalink / raw) To: linux-arm-kernel Add minimal support for the new sama5d2 Xplained board. Only USB, sd/mmc, ethernet and uart/usart peripherals added. With this DTS file you can boot the board and begin to play with it. Rootfs on NFS and sd card have successfully been tested.

* [PATCH 3/3] ARM: at91/dt: add minimal sama5d2 Xplained board @ 2015-06-18 13:18 ` Nicolas Ferre 0 siblings, 0 replies; 18+ messages in thread From: Nicolas Ferre @ 2015-06-18 13:18 UTC (permalink / raw) To: Alexandre Belloni, Jean-Christophe PLAGNIOL-VILLARD, Boris BREZILLON, Ludovic Desroches, linux-arm-kernel Cc: linux-kernel, Nicolas Ferre Add minimal support for the new sama5d2 Xplained board. Only USB, sd/mmc, ethernet and uart/usart peripherals added. With this DTS file you can boot the board and begin to play with it. Rootfs on NFS and sd card have successfully been tested.
