Hi, > items: > maximum: 24 (or 23?) I do not exactly get what you mean with this and how you get to 24, which isn't the maximum of the kbc-row-pins, but the maximum of kbc-row-pins and kbc-col-pins added. I would be glad to get some more clarification abou that. Additionally thanks for yll the feedback so far, really appreciate it. regards Max Buchholz > From: Max Buchholz <Max.Buchholz@xxxxxx> > > This converts the Nvidia Tegra keyboard controller bindings to YAML > and fix them up a bit. > > Reviewed-by: David Heidelberg <david@xxxxxxx> > Signed-off-by: Max Buchholz <max.buchholz@xxxxxx> > --- > v3: > - fixed maxItems for array properties > v2: > - rework the file according to the feedback > > .../bindings/input/nvidia,tegra20-kbc.txt | 55 --------- > .../bindings/input/nvidia,tegra20-kbc.yaml | 111 ++++++++++++++++++ > .../bindings/power/wakeup-source.txt | 2 +- > 3 files changed, 112 insertions(+), 56 deletions(-) > delete mode 100644 Documentation/devicetree/bindings/input/nvidia,tegra20-kbc.txt > create mode 100644 Documentation/devicetree/bindings/input/nvidia,tegra20-kbc.yaml > > diff --git a/Documentation/devicetree/bindings/input/nvidia,tegra20-kbc.txt b/Documentation/devicetree/bindings/input/nvidia,tegra20-kbc.txt > deleted file mode 100644 > index 1faa7292e21f..000000000000 > --- a/Documentation/devicetree/bindings/input/nvidia,tegra20-kbc.txt > +++ /dev/null > @@ -1,55 +0,0 @@ > -* Tegra keyboard controller > -The key controller has maximum 24 pins to make matrix keypad.
