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

From: [email-masked] (Cyrille Pitchen)
Date: Mon, 20 Jul 2015 10:54:05 +0200

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
