Convert lpc32xx-key.txt to yaml format. Additional changes: - set maximum of key-row(column) to 4. - add ref to matrix-keymap.yaml. Reviewed-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Frank Li <Frank.Li@nxp.com> --- change in v2 - add ref to matrix-keymap.yaml. - remove properties, which already defined in matrix-keymap.yaml. - Add Vladimir Zapolskiy review tag --- .../devicetree/bindings/input/lpc32xx-key.txt | 34 ----------- .../bindings/input/nxp,lpc3220-key.yaml | 61 +++++++++++++++++++ 2 files changed, 61 insertions(+), 34 deletions(-) delete mode 100644 Documentation/devicetree/bindings/input/lpc32xx-key.txt create mode 100644 Documentation/devicetree/bindings/input/nxp,lpc3220-key.yaml
