The Microchip 48l640 is a 8KByte EERAM connected via SPI. Add devicetree bindings documentation. Signed-off-by: Heiko Schocher <redacted> --- I must admit that I created the file Documentation/devicetree/bindings/mtd/microchip,mchp48l640.yaml by hand, looking into other yaml files... Is there a way to check such a file to its correctness? .../bindings/mtd/microchip,mchp48l640.yaml | 40 +++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/microchip,mchp48l640.yaml
