ARM: at91/dt: add SAMA5 trng nodes

Adds support for the true hardware random number generator.

Tested on a SAMA5D3 Xplained board.

Mike Williams (3):
ARM: at91/dt: sama5d2: add trng node
ARM: at91/dt: sama5d3: add trng node
ARM: at91/dt: sama5d4: add trng node

Oh, Mike, something is missing here: you Singed-off-by tag.

Please read this and send me an email telling me if you add it to your patches (this way you don't have to re-send them, if it's easier for you).

Bye,

Oh, yes: they were missing indeed.

BTW, I reduce the size of the register memory map to 0x100 like this on all patches (no need to re-send):

and take advantage of this to do the same on
arch/arm/boot/dts/at91sam9g45.dtsi as well.

Thanks and:

I stack the patches on top of at91-4.7-dt and build a pull-request soon.
