Subject: [PATCH v3 0/3] ARM: at91: introducing Atmel sama5d2 SoC

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. Some of these patches are already in linux-next
and other are progressing 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 or QSPI for instance). Stay tunned for more fun!

Changes in v3:
- collect Ack by Alexandre
- remove sd/mmc nodes
- remove generated clock nodes

Changes in v2:
- change the meaningless config HAVE_AT91_GENERATED to HAVE_AT91_GENERATED_CLK
- modify README file for clarity
- fix sdmmc clocks and memory range
- add flexcom and audio Class D amplifier peripheral clock definitions
- add qspi peripheral clock definitions
- add more generated clock definitions
- fix DMA definitions for crypto peripherals
- add spi, i2c and rtc nodes
- enable spi and i2c nodes
- enable sdmmc0
- move to stdout-path for console

Subject: [PATCH v3 3/3] ARM: at91/dt: add minimal sama5d2 Xplained board

Add minimal support for the new sama5d2 Xplained board. Only USB,
spi/i2c, 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.

Signed-off-by: Nicolas Ferre <[email protected]>
Acked-by: Alexandre Belloni <[email protected]>
---

Changes in v3:
- remove sd/mmc nodes

Changes in v2:
- enable spi and i2c nodes
- enable sdmmc0
- move to stdout-path for console
