Hi all,
This series adds support for sama5d2 SoM1 devices.
The at91-sama5d27_som1.dtsi add specific bindings for SoM1 board.
The at91-sama5d27_som1_ek.dts add specific bindings for SoM1 EK board.
The sama5d27_som1_ek uses a EEPROM binding, "start-offset", which is
introduced in patch series: "[RFC PATCH 0/3] Add at24 functionality to
read form different EEPROM offsets".
Thank you,
Claudiu

Is there any publicly available information on this SoM?

I am wondering if it's a good idea to give the flash map here. If we
take a kernel generated by a sama5_defconfig, it is about 3.8 MB.

Are you sure about this value? pinctrl tells PD31 so 127. By the way, it
is better to use macros: PIN_PD31.

Even if it is not done in other dts file (I plan to send patches to fix
it), prefer macros to avoid errors: PIN_PD20.

The flash size here is 8MB. With kernel image of 3.8M, bootloader of 18KB,
u-boot of 2.2MB, dtb of 31K it will still fit.

Yes, here is a mistake. It has to be PIN_PD31. I will fix it in v2.
