Since you're changing that, Tegra should be capitalized in free-form text.

This seems a little long-winded. Perhaps just say:

SoCs
-------------------------------------------

Each device tree must specify which Tegra SoC it uses, using one of the following compatible values:

nvidia,tegra20
nvidia,tegra30

Boards
-------------------------------------------

Each device tree must specify which one or more of the following board-specific compatible values:

ad,plutux
compal,paz00
nvidia,harmony
...

(and keep the list alphabetically sorted)
