Hi all, V2 of this series adding octal SPI-NOR support to Mobileye EyeQ5 platform. It has been tested on EyeQ5 hardware successfully. V1 cover letter [5] contains a brief summary of what gets added. There is no dependency except if you want zero errors in devicetree: system-controller series [3] for <&clocks> phandle.
