Subject: [PATCH 0/2] ARM: at91/dt: add support for at91-kizboxmini

Hi,

Here are two patches to bring support for a new hardware based on SAM9G25 SoC.

The first one adds the PIN controller definition for PWM0.
The second defines the new board.

Best regards,
Gaël PORTAY (2):
ARM: at91/dt: sam9x5: add pinctrl for pwm0

I would remove "atmel,at91sam9g25ek" and "atmel,at91sam9x5ek". However,
you could use "atmel,at91sam9g25".

I do think so... I added them for consistency only... I will drop them
in v2.

Do you want I drop all those kind of comments (of the whole file) as
well ?

Thanks for your review.

I don't think it is necessary to do that change for the whole file yet,
let's just avoid adding more.
