[PATCH v3 0/2] Add support for Amediatech X98Q (Amlogic S905W2)

[PATCH v3 0/2] Add support for Amediatech X98Q (Amlogic S905W2)

[christian.koever-draxl]

From: Christian Stefan Kövér-Draxl <christian.koever-draxl@student.uibk.ac.at>

Changes in v3:
- Change position of the entry in the amlogic.yaml.
- Change formatting of the Amlogic W150S1 Wi-Fi module comment.
- Fix several formatting issues.

Changes in v2:
- Split dt-bindings and dts changes into separate patches.
- Updated model string to match documented vendor prefix.
- Put vddio_sd states array in a single line.
- Added a comment for the unsupported Amlogic W150S1 Wi-Fi module.

You should explain what the Amediatech X98Q is. You did this in the v2's
cover letter, but it should additionally go in here too so it's visible
in git commits in the kernel. What hardware does it have? Maybe also what is
enabled in the DT?
