Subject: [PATCH v2 00/11] spi: cadence-qspi: add Mobileye EyeQ5 support

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.

Have a nice day,
Théo

Changes in v2:
- Rebase upon v6.9-rc2.
- Fix dt-bindings commit subject tags.
- Take Reviewed-by: Krzysztof Kozlowski on dt-bindings commit.
- Add dt-bindings commit to order compatibles alphabetically.
  adding EyeQ5 compatible can be taken alone easily.
- Drop patch taken upstream:
- Add To: Rob Herring, following get_maintainer.pl recommendation.
- Link to v1: https://lore.kernel.org/r/20240308-cdns-qspi-mbly-v1-0-a503856dd205@bootlin.com

Krzysztof: unsure if you want this. It is second so that commit
