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!

Only the basic support for this new Atmel Cortex-A5 SoC. A subset of the
peripherals is setup to allow booting.
IRQ, clocks, USB, sd/mmc, crypto, timers, ethernet and uart/usart peripheral
nodes are added.

* [PATCH 2/3] ARM: at91/dt: add basic dtsi for 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
From: Ludovic Desroches <ludovic.desroches@atmel.com>
Only the basic support for this new Atmel Cortex-A5 SoC. A subset of the
peripherals is setup to allow booting.
IRQ, clocks, USB, sd/mmc, crypto, timers, ethernet and uart/usart peripheral
nodes are added.

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.

Shouldn't that go directly before or after the sama5d4 family ?

I think that at some point we'll have to kill those AT91_DEBUG_LL_*
which are actually board specific and not soc specific. I already have a
patch for that that I need to rebase.

This is "after" sama5d4: I sorted this file according to SoC release
date whereas I sorted the other entries in alpa-numerial order (sama5d2
placed before sama5d3).
Is it what you answered?

Ok, it could definitively simplify the last weird bits of our

Absolutely, I changed it to HAVE_AT91_GENERATED_CLK which is somehow
better. Also changed in my "generated clock" series sent to Boris.
Thanks for your review. Bye,

This is "after" sama5d4: I sorted this file according to SoC release
date whereas I sorted the other entries in alpa-numerial order (sama5d2
placed before sama5d3).
Is it what you answered?

Ok, it could definitively simplify the last weird bits of our
sub-architecture ;-)

No, I meant doing something like:
* ARM Cortex-A5 + NEON based SoCs
- sama5d4 family
- sama5d41
- sama5d42
- sama5d43
- sama5d44 (device superset)
+ Datasheet
http://www.atmel.com/Images/Atmel-11238-32-bit-Cortex-A5-Microcontroller-SAMA5D4_Datasheet.pdf
- sama5d2 family
- sama5d27
+ Datasheet
Coming soon
Else, you end up with two "ARM Cortex-A5 + NEON based SoCs" sections.

Oh, yes. Sure, I'll modify this.
Do you think that it's worth sending another series or I can take it for
the pull-request when it's modified?

Actually, I realized that I have some more nodes to add to the DT
descriptions, to it's worth sending a v2 of this series...
