Subject: Re: [PATCH 6/7] Documentation: atmel-quadspi: add binding file for
 Atmel QSPI driver

Hi Sergei,

thanks for the review. For the next series I've removed all references to
"qspi" in the node example but the one from the compatible string.
I've also removed the leading 0 in the size of the second memory region.

Best Regards,

Cyrille
