Add device tree probe support for atmel at_hdmac DMA driver.
Bindings are added to specify the number of channels that the implementation of
the controller actually has. They also allow to tell if the peripherals/DMA

Hi,
As a showcase, this is a basic device tree support for at91 SoC.
It add at91sam9g45 SoC with its Evaluation Kit board descriptions.
Only the dmaengine driver is converted at the moment so the support
is fairly simple.
Nicolas Ferre (2):
AT91: dt: at91sam9g45 family and board device
Create a new device tree source file for Atmel at91sam9g45 SoC family.
The Evaluation Kit at91sam9m10g45ek includes it.
This first basic support will be populated as drivers and boards will be
converted to device tree.

Hi,
Here is a first attempt to add device tree support to atmel_serial driver.
RS485 data are not handled for the moment. My feeling is that they should be
added as a generic DT biding set.

bootloader).
There is a "work in progress" snapshot of this work in at91 git tree/branch:

Pinctrl/pinmux is beeing built these days: stay tuned on

So what? We still keep the compatibility if the new SoC has it
compatibility assured with previous revision: there is nothing to modify.

No, it does not have to be exposed to the user: these data are highly
dependent on the actual hardware (IP revision in fact). So, no need to
mess with platform data.
So I will acknowledge Ludo's patches.

Yes, Ludovic shall keep i2c-gpio at the side of the new twi driver.
But for the platform, the platform maintainer will have to choose the
one or the other.

Seems ok from an AT91 perspective.
I know little about audio + DT integration, so I am not judging this part.

Seems ok for AT91. But will certainly need more eyes for the audio part...
