Ok cool. Please add min/max of 1 to 15 to the binding.

I was aware of this guideline, but I thought it only applies to the
summary line.
I'll apply the guideline to the whole description.
Thanks!

The maximum is 15.
There is no definition for the minimum - we can probably say the minimum is 1.

Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
to do frotz", as if you are giving orders to the codebase to change
its behaviour.

Is there any minimum/maximum number of elements possible?

[PATCH v4 1/2] dt-bindings: input: cros-ec-keyb: Add a new property

2021-01-07 Thread Philip Chen
This patch adds a new property `function-row-physmap` to the
device tree for the custom keyboard top row design.

The property describes the rows/columns of the top row keys
from left to right.

Signed-off-by: Philip Chen 
---

(no changes since v2)

Changes in v2:
- add `function-row-physmap` instead of `google,custom-keyb-top-row`
